We have 95db on swedish tracks :( do you think your exhaust will make it with a resonated midpipe? :)
And how much to Sweden? :)

i saw at tsukuba some louder FD's custom made their tips to point downward away from the db meters.

sure you could send me a tip to start with.. oh and some gaskets i made one out of rtv...:naughty:

ya honestly thats the only problem other than that i like it but it dose cause your check eng light to come on bc the ecu cannot tottaly cope with the loss of back pressure and if you let your car idle for a while it gets kinda rough, but then again i have the rb dual resonated mid as well. i might have to get a cobb tuner to fix that..

Probably not. Possibly if used with a catalytic converter. Shoot me a pm with your zipcode and I can quote you shipping.

No tip!?!?!!? There was no little brown box? if so that explains everything I could have sworn that I put that box in there. It has the tip, hardware and gaskets....

You sir, are a compete idiot. First off why the hell would you install an exhaust without all the parts. Would you put in an engine without everything installed correctly...oh wait yes you probably would.

Second, do you even understand anything about exhaust, loss of back pressure causes the CEL to come on?!?!

With your level of intelligence you shouldn't try to install anything yourself, you are clearly a danger to yourself, and probably everyone around you.

I've been looking at this exhaust for awhile now.

Couldn't wait any longer, placed a order for the cat back and some EVO-R endlinks. Can't wait to get them! :ylsuper:

The front endlinks are back ordered. I will ship the exhaust out by itself.

Can you please double check the big box that the exhaust came in, there should be a 6x4x6 box with the Tip, gaskets and hardware in there. I just double checked my inventory and I am not extra those above items so the items were sent in that box. I know the box can be lost in the sea of packing peanuts.

comebackqid 01-02-2012 02:23 AM

I'm really considering this exhaust, but I was wondering if a dual is more quiet I heard single exit is louder? is this true? I live in california so I would like a fairly quiet exhaust cops out here hate pretty much anything that isn't domestic and from 30+ years ago

That's cool, I still got to get some shocks before I install anything.

Looking forward to hearing this exhaust on my car. :smoker:

jimtaylor89 01-04-2012 06:09 AM

wow ok you sir are an ass for one and i understand more than you ever will.. with the loss of back pressure the ecu cannot fully correct the fuel mapping for the loss of back pressure so.. you have to change you fuel mapping to do just that thats were cobb comes in for the light stuff and no i would not do an install with out all the parts that i needed the thermal resistant rtv was a good temporary fix for the gasket until i had one made and i had bought the proper hard wear before hand as well, but honestly if your just going to be an ass on here before you have any facts straight just dont post anything at all if you have a problem pm me and we can talk.

trust me i checked.. the box probally busted opened at some point during shipping and that little box might have fell out, either way i have it covered i did some measuring and contacted my engineering department while i was at work and they had the fabrication shop make me some gaskets and a tip in their spare time and it looks just the same as those in the pics that are supposed to come with the kit, even with the nice little blue tipping :)

:rollingla I suggest you do some major searching and reading and you will learn how stupid you are making yourself look.

Sorry Brice we don't mean to jack your thread but this guy is just too much. Back to the subject at hand, I really want your exhaust. Unfortunately the money I could have used to get it I ended up getting a whole new fuel pump assembly. When I do get around to it though I'd like to dyno this with a before and after comparison with the stock exhaust with mid pipe with all my other mods and will gladly post my results. I'll contact you about it later and maybe you can point me to a reputable dyno in the area.

A dyno in PSL? Where? The closest one I found was in Melbourne. Do you know what kind of equipment they have?

Z0oMzo0m 01-05-2012 03:48 AM

was an old friend, hes had it for years. your just looking for numbers so it would be ok, if you were doing any tunning id stay away. we call him Honda tom. basically what he covers.

but i couldn't tell you what equipment, i just know i pull my car up on it and accel. lol
i think he charges 60.00 for a few pulls. but i could be wrong its been awhile. if your interested let me know. i can try and get a hold of him

Race Roots 01-10-2012 10:41 AM

I am down to 2 exhausts in stock and ready to ship.

Johnvx1k 01-10-2012 11:39 AM

I posted this on the other thread for this exhaust, but I'll put it up here since I see people asking for videos. I love the exhaust. Didn't have any problems installing and its been good ever since.


1.3_LittersOfFurry 01-11-2012 11:24 AM

Mines in the mail, can't freaking wait! My apt complex is going to love me every morning at 4:30am when I warm her up. Haha!

Brice, any update on the endlinks? Still haven't picked a shock yet, so no rush, just wondering.

Asked Jay the other day about the endlinks, still waiting on a response. When he lets me know I will let you know.

1.3_LittersOfFurry 01-14-2012 06:40 PM

Exhaust came in yesterday, looks like everything is here. Should be installing Monday or Tuesday. Thanks Brice.

yomomspimp06 01-15-2012 09:42 AM

hurry! I wanna hear the sound with the gutted cat

1.3_LittersOfFurry 01-15-2012 10:15 AM

I'll post a video when I get it on. Might try to install it today if I got enough daylight after work. Gf already bitching cause I got it laid out in the living room and I won't let her move it. Lol

yomomspimp06 01-15-2012 04:46 PM

^haha

1.3_LittersOfFurry 01-15-2012 10:15 PM

Got it on! :rock:

Ran into a few problems, none were the cat-back's fault though.

Broke both of the spring bolts, and for some reason the nuts were welded or something to the flange. We had to drill the holes out which was not fun at all. But now it's on. :D:

So, my opinion, the quality is great. Came with everything needed to install.

It's LOUD, very loud, but it sounds BAD-ASS, very bad-ass. Within 5 mins of starting it up to let it warm up I had 4 random people around the back of the car. After I got the tools picked up I went go give it a rev, by request, and then camera phones started popping up lol. Here are two clips I got off them, sorry for some reason the second clip didn't record sound. I'll post a better one in a few days.

1 exhaust left until next month.

1.3_LittersOfFurry 01-18-2012 12:05 PM

So 2 very small issues since the install.

1. Melted part of the exhaust shroud, but not bad and I was able to trim it away from the pipe and seems to be doing well now. It's the back part of the shroud, so you can't even tell I cut it.

2. Got a rattle at idle, sometimes. It looks like the pipe is hitting the frame by the diff. Maybe some header wrap around that area might fix the problem...

It has gotten a little quieter now that I fixed a leak. Still very happy with it. Waiting for a good day off to make a video still.

I have that rattle too, thanks for identifying where its coming from for me so i dont have to jack the car up :)

i heard somewhere the excessive use of wd40 can cause the hangers to slide around, i used pounds of that stuff getting the stock exhaust off:rollingla

1.3_LittersOfFurry 01-18-2012 03:50 PM

Well I wish I knew about that wd40 trick lol. I caught 7 kinds of hell taking the oem muffler off the hangers.

I might try to "stretch" that hanger by the diff. Didn't have a rattle problem till I finally got that hanger on.

EricB 01-18-2012 08:33 PM

mine has never seen snow :lol:

cant imagine how a rx8 that has seen snow must have been.

1.3_LittersOfFurry 01-18-2012 09:27 PM

^ Snow?

What is this snow you speak of?

Johnvx1k 01-19-2012 08:53 PM

Ok good I am not the only one with the rattle. I'll have to fix that this weekend when I'm installing my RB Midpipe. With the hangers I found it easier to just use dish soap.

Z0oMzo0m 01-19-2012 09:20 PM

i have had it on for a year, and i have no idea what rattle you guys speak of.. lol i havent had anything, besides my inner side of the shroud melt a little bit. but not visible from behind car.

Johnvx1k 01-20-2012 11:50 AM

Well I haven't had any problems with the exhaust shroud. I haven't noticed it at least, maybe I should check. I've had the exhaust for about half a year. I didn't notice the rattle until I made a video for the exhaust and heard it through the camera. Sounds pretty crazy higher in the rpm band. Maybe Z0oMzo0m just used some magic to install it different than I?

redline86 01-23-2012 09:49 PM

Ok so some of you guys got a rattle but not everyone, and some had issues with the shrouds. Could this just be a user install issue mabe or just variations in the product? I've heard some people had a lot of issues with the Agency power exhaust, but others had none. Just curious because I'd like to support a local vendor that seems to have a great product, but for 150 more I can get the HKS that I have yet to hear one bad thing about.

I have a rattle at idle that would probly be fixed by wrapping the part thats moving but i need to jack the car for that and i dont feel like it lol. I think its gotten worse between since i last posted about it and now.

when i first noticed it... I set my bose to level 2 volume and it covered it

Today driving home i had to set it at 4.

I have yet to check my shrouds but i dont think it is much of an issue.

I think the rattle may be from excess wd40 :p: ill have to jack the car up when it gets warmer to diagnose this.

The rattle im hearing sounds as if it is coming to the left of my driver side door or the door itself but when i put pressure on the door it doesnt stop, i think it may just be hitting something and sound is traveling.

Note the rattle im hearing is only coming on at idle and any gas and i mean anything applied will make it go away.

RRSingle and HKS Hi Power are very similar in design, i think the Hi Power might be lighter (Brice do you confirm?) but i dont think by much, and it doesnt matter to me because im not tracking my rx8 hardcore where i need the few lb difference... Also noting that since they are very similar in design they both give off very similar tones that you wouldnt be able to tell unless revved side by side.

What i dont like about the hks is that their tip doesnt say HKS on it or anything, for anyone knows it could be a ebay exhaust. Though i think the hks tip is a Ti where the RR is a Ti painted finish on Stainless steel.

These things are what make up if the +$150 is worth it to you.

Really hard to tell on each customers installed application. I have seen that the exhaust hangers play a huge role, so if a customers is more worn and flexible more movement would occur.

Replacing those hangers with Poly would be a solution to reduce the movement of the exhaust.

1.3_LittersOfFurry 01-24-2012 02:22 PM

^ Brice, mine seems to be more the hanger is holding it to high (to close) to the frame near the diff. I had no rattle till a day or 2 later when I finally put that last hanger on by the diff.

I plan on fixing it, just not now. I've been super lazy since installing it. :lol:

Thats would make a lot of sense. Some of these guys could have hangers that are 8 years old. I will def. replace them at the same time with a new exhaust.

Could that play in movement also be the cause of melted shrouds?

Either way, RR or HKS I'm gonna purchase it through you. Everyone who has it seems to be happy with the over all build quality and the sound. I'm just nit picking on the fine details thats all.

Z0oMzo0m 01-24-2012 07:17 PM

Redline, I have it and im close to Vero, we can meet up sometime and you can see what it looks like in person, sounds may little different due to my midpipe but you will get the idea :) let me know

Shoot me a Pm, and i can give you my number

Pm'd, I have the same mid pipe so that would really give me a good idea of how it sounds and that way I can get a good look at it as well.

firecran 01-24-2012 08:55 PM

No problems at all with mine....I highly recommend it.
Also, I really like being different with the single tip design.
