GReddy just received a shipment of their New-Release SP2 full stainless steel cat-back exhausts the other day. You can contact your local retailer for more info on pricing, etc...

I've had the exhaust on my car since Aug. 9... the day after I purchased the RX8, so I can't really comment on the effects it has had over stock.

If you're in the Orange County, CA area, one or two of you are more than welcome to take a test drive and post your opinions - it is my only power modification to date. PM me if interested.

Rob

... I'll try to get under-car photos of the can and piping...

dude those tips are F*CK*NG HUGE!!! might be the angle, but they might be a little to big for most people's liking.

:( ewww...

Well, I LIKE it. Call me twisted. :D

How about a sound file?

Well I like it ......now just need to see how much it is and how it sounds

Sweet as sin...those tips rock!

how much did this exhaust run you?? its the first ive seen by greddy for the 8, it looks very nice


andrew

Re: Price Paid... the exhaust was a prototype from GReddy...

My offer still stands from above: If you're in the Orange County, CA area, one or two of you are more than welcome to take a test drive and post your opinions of the exhaust- it is my only power modification to date. PM me if interested.

Aren't those pipes awfully close to the plastic? Wouldn't enough heat deform them?

That was a worry I had at first, but one I've long dismissed... there're no scars, pits, or mars on the surrounding plastic of any kind. However, the exhaust temperatures have made the tips turn a tinge of gold... something you'd have to see in person.

So far I've done 6000+ mi. of driving, to include two 19-hour no-rest road trips from Los Angeles to San Antonio and back.

Need a sound clip posted here...... PLEASE!

when will this be released from greddy to the public?

-Mr. Wigggles

that tip is way to big for my liking, i mean im sure itll sound like every other greddy exhaust and all which is a nice tone, but... that tip is over doing it

i like greddy mufflers...all of their products are dyno proven to make a substantial amount of power...as far as the tips go i think it looks good..those 4/12 tips or 5 inchers?

the greddy exhausts usually look nice, but from that picture it looks a little awkward.

sound clips? :)

is it CA street legal or an off-road only unit? I heard exhausts had to be under 85 dBs. Out of curiosity, is the unit made in the US or Japan?

dont kill the messenger if im wrong but i think its 93 db is the limit

They're manufactured in Japan. As a cat-back system, the SP2 exhausts conform to decibel limits under 95dBa... IOW, they're CA street-legal.

the tips are ~4.5" diameter.

Here's a sideview of sorts:

I saw and heard your greddy exhaust yesterday
you were at the block around 3pm

Oh man for crying out load! PLEASE PLEASE PLEASE POST A SOUND CLIP! Those looke awsome!!! Just need to know how it sounds:S

How'd it sound Mike?

Sounded deep as hell
I like it

deeper than the Borla's?b/c im looking for a deep sound

oh ya how much?

For the love of god .. sound clip please !!


**Updated** 31Dec03 -=No longer need a sound clip!! ITS AWSOME!!!=-

Soooo...................no sound clip yet or price?

Sorry... my digicam w/sound capabilities took a poop. I was hoping someone would bring something to the local meet tonight, but it was a no go. As far as pricing... you can check out http://www.optauto.com/webstore/product_information.asp?number=TP-10147000&variation=&aitem=1&mitem=1&back=yes&dept=4004

I'm sure other retailers will start carrying them soon, as well.

Rob

love greddy, and not to bad on the price considering my exhaust on my eclipse before i turobcharged it was about 600.00 for the evo model. good find.

Actually here is a better pic
The exhaust has not been released yet but I will have a few as soon as they are. I should have some at the beginning of January.

Jason

I just called two import shops in cali
one shop quoted $470 but said its on back order for a month
the other shop said price is to be announced

You got mis quoted on the $470. Unless they are selling them near cost. :)

Jason

rx7.com has an exhaust with video for it! It's pretty cool. I'm not sure I'd buy it, but it sames good. Sort of loses the exoticness of the stocker I think.

HELLO you said with a VIDEO

LOUD!

I hear nothing

The vid worked for me.

yeah, that is pretty loud - but that was the catback AND midpipe. So, if you're looking to use canzoomer's stage2 tuning, that's the type of volume you can expect. A bit much for my needs, but RP knows their stuff and I have no doubt that theirs is a well-tested and superbly-matched setup.

Am I missing something? I see no video or link and hear no sound.

http://www.rx7.com/RPGReddyRX8exhaust/index.html

pretty cool but that is like instant ticket material tho. every cop is suburbia will zero in on that faster than when krispy kreme has a give away.

i like it, i think it sounds nice



andrew

So the mid-pipe is $350, what about the muffler?

CANZOOMER are you looking at this?? How will your Stage 1 kit work with this? And better still, how will your Stage 2 take advantage of it? Oh I can't wait to get all this mods!! (But I need to get the car first) ;)

Sounds great. I think i found my exhaust.

thats awesome... i wish i could afford something like that

Mike,

Can you e-mail the places? I have cash burning a hole in my pocket for an exhaust system.

Matt

nice......now need some sound clips and what about the drone if any...you said you took some 19hr trips..was the sound monotenous? I had Greddy SP exhaust on my Integra and it sometimes was annoying on the freeway....what's your experience with it on the 8?

my friend has exhaust and gets annoying sometimes after awhile..but i just need a sound clip to comapre gready and borla

so u have to buy it spearate the midpipe? so you have the buy the midpipe and mufflers? how much is that total

"first header-back exhaust system for the RX-8"
what does that mean?

In case anyone misses the point that this is not a street-legal cat-back system, be sure to read the small print:

"This pipe eliminates the catalytic converter. As such, this pipe is sold only for off-road or racing purposes."

It'll void your warranty. Does sound nice though...

Is this avaiable now

Thanks Mike.

I owe you one.

RotaryPerformace, Garland,TX? Thats like 30-45 mins from me...I need to find out where the hell that is.

"first header-back exhaust system for the RX-8"

That means the system replaces the stock midpipe as well so you'll be running catless.

here ya go guys..the clip...im suprised no one on this post has heard it.... http://www.rx7.com/RPGReddyRX8exhaust/rx8midpipemufflerclips.html

Yup. Saw it in person today. I like it! Good thing tomorrow is payday! :D And the installer is 2 blocks from work. Even better. Plus the guy is giving me a great price on the unit. I like the oval shaped tips and the slight angle cut on the side. I hope it sounds as nice as the HKS did. SHould be quiter than the video posted since I wont be removing the cat anytime soon.

Thanks Alex! If anybody needs to buy a hard to find exhaust, just let Alex find one for him and buy it when he lets you know about it :D

I went to pan auto and they had one on hand. It look really nice. I told them I would be getting it sometime next month. Let us know how it sound and how loud it is. What the hp for the greddy system? Can't wait.

I saw 22HP but thats with the test pipe, so no cat. I aint doing that :D

I will eventually get the car dynoed but I want the sound and look more than anything right now :D

good deal...let me know what you think...

im still stuck between Greddy, RB and B&B...

Doh!
you..you....arrrg

oh well call me when it's getting put in! I'm sure Armando will be running over too. We'll get the video clip, and this time give you the Memory Stick so it can actually be posted ;)

Welp, I got it! Weee!

First impressions, the tips are pretty big once on the car. I do like the shape on them, they are just a triffle large. Sound however, is MUCH improved. Sounds very similar to the HKS, although it's got a slightly deeper rumble when idle or low throttle. Closed windows it's barely there until you hit it. With the windows open it's a little more noticeable. It's nowhere NEAR as loud as the previous greddy clip posted that had the test pipe as well. I only have my film camera handy and I snapped some pics. Soon as I find my digi cam I'll get some more :D

So hopefully finally this weekend we'll get the new HKS and Greddy clips up.

Any changes in performance with the greddy exhaust on

ugh...you suck...

you must not be married...or you got a chick thats into tuning...hopefully i will have some influence on my 6mth old daughter; that'll be 2 against the wife for car parts.....

I called GReddy and asked them about this exhaust and they said they didn't have any yet and that made 8-9 H/P. Same as the Borla. I'm still liking my B&B.

Congrats Yuri, The exhaust looks GREAT, the tips are huge!

It is a bit louder than the HKS, and not quite as deep. That said, it still sounds great! Not at all Raspy or annoying, and yes the butt dyno feels a difference. Get those pics up soon :D

Pics I took at instal where with a reg camera. I am borrwing the in-laws digicam tomorrow tog et some pics up then as I still have way too many pics on the roll to just develope it for 3 pics :D

After I saw Alex I promptly cruised on the turnpike for 40 miles and at cruising speed (85MPH) it is barely there. You CAN hear a slightly louder rumble if the stereo is off, but any music drowns it out so it isnt anoying. You can also feel the grumble a little more in the pedals. All in all I am VERY happy with it. I felt like maybe there was some extra power there, but it was very slight IMHO. I would beleive 8-9HP as vivid stated.

Hey guys i know you are in miami, let me know when you guys get together id love to be there to hear the 2 side by side, send me an email so i can meet you guys

Hey guys,
for those who wanna hear the GReddy pipe....
here's a repost i done few days agao (my bad) that mightl interest u!!!:D

http://www.rx7.com/RPGReddyRX8exhaust/soundmovieclips.html

Gecko: Thats with a testpipe though. The plain catback is not as loud. As soon as the damn batteries finish charging, I'll post the vid clip. Here's some pics in the meantime...

great pics

Addition! Sound is at

Practically pitch black outside vid clip (no one to hold camera so it's on the ground) in MP4 (prolly need quicktime to play it, can do something more compatible tomorrow) is at

http://www.cisgroupintl.com/yuri/dark.MP4

You can hear my radar beep when I start the car and thats inside the car above my dash. So you can tell it's NOT that loud. The camera is laying all of 2 feet from the exhaust, but on the side, not directly behind the car.

Thanx for that, I love sound

hehehe I can hear this in person!

ok I got my GReddy Street Performance cat-back exhaust system today and I am stoked! Here is what I got straight from Trust Japan. Got it at 5pm, installed right after! Box is flat, and quite wide and long (like if you shipped a painting on canvas).

1) Greddy Dual Muffler with dual tip exhaust w/ Greddy embossed tip
2) Cat-back piping to the muffler. (Attaches to the resonator flange)
3) Greddy Warranty, Trust warranty, Survey, 2 Nuts, 2 Lock Nuts, 2 Bolts, 2 Washers, and 1 Plastic Metallic Greddy "Exhaust System" badge.

All nicely packed in with good cushioning from foam.

Initial Impressions - The Tips are quite big, about twice the size of the stock ones, and have a little lip on the edge. Chrome silver finish with nicely welded connections that gleam different colors such in the light.

Install - A TOTAL Bitch if you do it yourself with Jackstands and a Jack... let me tell you it took approximately 3-4 hours to do this install - but its worth it! The rubber hanger holders are totally annoying. HIGHLY suggest letting an exhaust/muffler shop do the install for like $60 cuz its worth it! UN-INSTALLING THE STOCK EXHAUST SYSTEM was the worse part, installing the GReddy system took approximately 30 mins. A real simple bolt-on procedure.

Some TIPS FOR INSTALL - Jack car up as high as possible. Take the black rear section that holds out the exhaust tip and rotary crest on the rear bumper off. The little clips that hold it in are very annoying - suggest using small screwdriver and plyers to take them out. WD-40 or Valvoline lubricant can aid in the seperation of the hangers and the hooks that hold the exhaust up.

1) Need 17mm deep socket
2) Socket Wrench
3) Flat Head Screwdriver
4) Plyers (needle nose)
5) Grippy device
6) Shop Light
7) Jackstands/Jack
8) Creeper
9) Protective Glasses
10) Gloves
11) Friend helps too!

OK THE BORING PART IS OVER! (just want to be thorough!)
-----------------------------------------------------------------------------


DRIVING TEST
Cold Start - in California weather - night, approx. 11pm coastal area with light mist and about 60-70 *F temperature. Hilly to Flat. 2004 RX-8 STOCK with GReddy SP Exhaust. 2 passengers. 6 speed transmission. 7500 miles Odometer reading.

From the start I could feel an increase in power at low RPMS meaning under 3500 rpm, then there is like a "dead" spot at about 4000-4300 rpm, then as the secondary ports open up and the 2nd intake tract activates at approximately 4500 rpm, you can feel the increase in performance all the way to 9000 rpm. Not like a huge increase but a nice little nudge, not a head snapping jolt.

Sound is pleasant to say the least. Low pitched tone with a nice little woosh when shifting.

Idle is slightly louder than stock, with a nice hum.

Regular driving and shifting under 4000 rpm, nice sound, but not a roar at all, conservative and inconspicuous but louder than stock.

Spirited driving very loud and roars after the ports open up. It sounds like a real race car. Not like a cheap exhaust muffler or system, sounds very "racey" for lack of a better term. When I got to higher rpms after around 6000 rpm, the car pretty much is where the sweet spot is for this exhaust. The performance is really felt in my opinion and for some odd reason it seems to climb to 9000 rpm a bit quicker than normal even with a passenger load.

RICE FACTOR! - My friend used to have a riced out Accord (which he admits is riced out) and he says the GReddy SP Exhaust it doesnt sound ricey at all. And he should know since he is the king of rice! And has been in the import scene for years and knows what "rice" sounds like.

Driving down the infamous Pacific Coast Highway (Highway 1) in California coastal parts was awesome with this mod. Not only did a brand new Brabus Modified C-Class Mercedes-Benz want to race me, but it turned heads, and people were doing the booty call beep with their alarm at me. Definately adds to the look of the RX-8 from the rear and sides. The tips are large, but they do not look stock, nor flashy.

Why did I buy this exhaust?
Excellent price, its JDM, nice look, excellent performance gain, reputable manufacturer and quality, and its legal emission and decibel wise. It meets all my quotas for an exhaust and it came through with flying colors!

Sound - 5/5
Price - 5/5
Performance - 5/5
Appearance - 4/5
Quality - 5/5


* will post pics in a day or so, anything you would like to know, just ask!

Hope this helps!

I'm glad that you're enjoying your new exhaust... "booty call beep?"

Thanks for the detailed report. Look forward to the sound clip.

thanx for the post. Have you compared the sound to Borla? Can't wait for a clip!

hehehe I can hear this in person!

Efini 8, is the sound clip an accurate representation of how it sounds to you?

Sounds sweet good buy, maybe Santa will bring me one!!:D

There is already another sound clip for this exhaust posted by Genom in the "getting a GReddy" thread for anyone that can't wait.

Great post though ;)

Get the sound clip to see if there is any difference between recordings.

The rubber hangers are easiest to deal with if you spread silicone grease on them. Try to keep it off your hands though, as it will make it hard to hold on to anything. BTW, the silicone grease stops the rubber from aging (hardening) and extends its' life.

Great post, great exhaust! It'd be interesting to see if the tips will discolor to a goldish-hue after awhile like mine have, or if GReddy addressed that during production. It took approx. 1500 mi. of driving before they did, though. Let me know!

whats happening to ur car at tony's shop rob? I heard that the dude that bought ur wrx blew the motor and is changing the color of it and stuff. After u installed it did idle from a cold start go up and down repeatatively without modulation of the acclerator pedal?

nice write up thx

greddy is a great company but my last exhaust from them the evolution did discolor to a goldish color also

hmmmm it sounds a lot different in person, thats odd.

the goldish tinge I believe is part of the composition of stainless steel. If you take a look at other stainless steel objects a goldish tinge as well as silver, purple, green, yellow are visable. I believe its just a characteristic of manufacturing process of stainless steel or the components of its material nature.

it's a beep that kind of sounds like ur alarmed just activated. usually used to tell someone you're there witout using your horn.

Great write up. I can't wait to get an exhaust on my car.

Whats the diameter on the Greddy piping?

the exhaust piping under the car or the muffler tip?

before the muffler

Guess no one knows??

Howcome NO ONE can tell us what diameter the GReddy piping is? Sheesh.

Because we put the unit ON the car. It's not sitting on a desk to measure whenever someone feels the fancy to know about it. Why not do the smart thing and a: look for it on the greddy website, or b: Call Greddy and find out in all of 2 minutes rather than bitch at people you dont know?

I think its about 3 inches. sorry for delay... some people have a life you know ... lol

Why can't you not be a dick?

I have checked GReddys site, and thousands of others, my statement wasn't directed only at you. Stop being an ass.

I was under the impression that people would like to know things about products before they buy them, or could be so kind as to pop under the car with a god damn ruler for 20 seconds...

What is the difference between SP2 and EVO exhausts?

What happened to Trust Exhausts? I can only find Greddy... I know they are the same, but I like the "Trust" name better.

where did you attach the ground wire from the original exhaust when you installed the Greddy or did you jsut remove it all together?

Rigth!! what is the difference? in sound?
from which site can take a GReddy EVO??

I installed the Greddy this weekend. If you are not on a lift, it can be tricky getting the exhaust off. I could not get the pipe off that runs up towards the cat and had to take off the plastic exhaust openings to get the tips to slide out so I could get it off. The Greddy weighs about 5 lbs less than stock. It is LOUD. I have no resonator so it is quite loud. Much deeper tone, no more raspy, tingy sound. The vibration sound is totally gone too. I had a vibration tingy sound from 4K-5K and that is totally gone. The ground wire is still an issue. Not sure what to do with it yet. I wrapped it around one of the exhaust hangers for the time being. I am going to try another video soon.

I did mine about a month ago, very easy to come off after I removed the 5 hangers and the plastic around the exhaust tips. As for the ground strap while mine ran fine for three weeks without it I figure Mazda put it there for some reason so yesterday I put it back using a clamp similar to this one around one of the mounting struts. I attached the end of the grounding strap to a small section of steel attached to this clamp. I will add a photo of mine later tonight.

EDIT: Pic of what I used.

http://www.mazdatrix.com/8exhaust.htm

This website has video and audio for a couple of the available exhaust systems. It helped with my decision, now to come up with the money.

I am waiting to get the SP2... coming from Japan to Greece :)

EDIT: Pic of what I used.

I am going to try the same, thanks for sharing.
