GReddy SP2 Installed
 

and I LOVE IT. Car sounds soo much better with it on IMO. Not loud like a pissed off bumble bee, a low deep growl loud is more of a better description. I did the install in my gargage with my brother and it only took 1 hour. Was not as hard as I thought and I saved some money by doing it myself. Car feels like it has a lot more pop IMO. Thanx for all the people that supplied me the info with concerning the install and quality. Anyway, I got the exhaust from http://revhighonline.com/ for $520 shipped. Excellent service. No need for extra shipping, like overnight or next day or something. I got my exhaust within 4 days including the day I ordered it. Well I am just so thrilled, I had to share my feelings with ppl that will know where I am coming from. Take care and happy revving.

congrats on ur exhaust.

I have the same exhaust and can't wait to test it out!

I love mine. Doesn't sound ricey like alot of people say. Just a nice smooth tone. And I love the pop when I shift @5-6k rpm. Good stuff.

I hope,too,one of these mulleniums,get a greddys because I would like mine to have that cool sound cruising my neighborhood, ohhhh yehhh ;)

Does it drone at highway speeds? Is it just a bit louder than stock? Im looking for an exhaust that sounds a little more aggressive than stock, that also looks good. The Mazdaspeed supposedly fits my sound requirement, but the tips suck.

No, it does not drone. I have had mine on since November and today was the first time I thought to myself, “ Self, this thing is loud”. It was in the high 70’s for the first time this year so I drove home with the top open, windows down. The exit off the highway curls around and under six lanes of highway and I had to step on it to merge. It was like driving in a small tunnel and it was LOUD! The echo of the SP2 in a tunnel @ 7,000 RPM sure sounded like I was driving a F1 car, nice but it was loud. Which brings me to the point if you need it be quiet just keep the revs under 4,000, but over that it’s loud, a GOOD loud.

Awesome... this is what I'm looking for. My Borla equipped Miata would sound like that going through under an overpass- not ricey, just low and loud... although it did drone with the hardtop on. I haven't been impressed with the sound of the Borla on the RX8 though, so I'm looking for the kind of sound you're describing.

Since you've had it on for a while now, have you seen any problems with melting around the rear-facia? My only hesitation is those Greddy tips are huuuge... is there enough clearance?

Thanks for the info!

I have the Exhaust Finishers ( waste of money IMO ) , had them before I got the SP2. So they are kind of ‘protecting’ the fascia, but others SP2 owners that do not have the finishers report there is no problem with melting. The only negative I can say is it hard to clean the Exhaust Finishers with the SP2 tips. Also the tips will turn a light gold color as a result of the heats effect on Stainless Steel. If you polish the tips with something like “ Never Dull “ it will not be as bad.

I've had my Greddy on since May '04 *and* I live in the desert where it's over 110 degrees in the summer. The rear-facia is perfectly in tact and still looks absolutely brand new. Not even a hint of any kind of problem. In fact if you look at the tips on the Greddy -vs- the size of those openings, they fit perfectly. Why on earth did our stock tips come so darned small compared to those large moldings anyhow? They'll looking shockingly huge to you at first but truth be told, I think they fit the openings perfectly. Had the stock tips not been so small, the Greddy's wouldn't seem so large :D As said above, the Greddy tips take on a golden hue quickly after installation (and is the one and only thing I'd change if given the choice). As far as sound goes, Greddy is the best choice in my opinion :cool:

Thanks expo and poolside... sounds like this is a no-brainer then. Sucks about the bronzing of the tips, but I saw the same thing on DMENAC7's Racing Beat exhaust, too... so I guess it's common.

great choice :)

Do any of you with the GReddy exhaust have a high flow cat? I've heard it with the straight midpipe on the Rotary Performance website, and thought it sounded good, but a little too loud.

I second that :)

Thinking about ordering RB or Greddy this week for my 'new' 8.
Can the stock exhaust be removed and the new put on by 'one' person???
I really don;t have any help right now and was wondering if this was possible.
Also, does RB and Greddy simply 'bolt on' with no new hangers or hardware?

Thanks

Alan

Yes, one person can install it and yes it is a bolt on job. You do need ramps / jackstands to raise the rear of the car and a basic set of metric tools. Hardest parts are removing the rubber hangers and the trim around the tips.

Whats the weight of the Greddy Exhaust?

I'm leaning more towards getting the Racing beat, but i dont like that its almost the same weight as stock... I hope the greddy takes acouple of pounds off!

Mike - sounds like we're in the same boat.....I also am leaning towards the RB but want to be sure there is 'some' sound difference from stock (for my $600)! From what I've heard, the Greddy is for sure louder.....but I fear it may be too loud.

Expo - THANKS.

I can't understand why Greddy is getting this "loud" rap. I've heard Borla & RB; both are louder than my Greddy :cool:

Is loud a bad thing? My Greddy is loud when I want it to be which is fine with me. Drive under 4,000 rpm and it's not that much louder than stock. Go over 4,000 and it is loud but not open exhaust loud. Unless you live in a big city the SP2 is a fine system that will not give you headaches. As for the weight the Greddy was about 2 lbs lighter than stock.

this website has the RB, Greddy, Borla and Mazdaspeed exhausts, with sound. Not sure what their setup is beyond the exhaust, i.e. midpipe, but they are good sound clips.

I finally pulled the trigger- I ordered the SP2 tonight.... Revhighonline.com for $524 and free shipping. Can't wait to get that puppy installed :D

Good luck, you're going to LOVE it. The only thing I recommend when installing, besides the rear of the car, jack the middle of the car up as well. It will give you more room to work with the Spring loaded bolts. Best of luck! Happy Reving!

Thanks... I wish they'd hurry up and ship it! : )

I'm planning on putting all four corners up on jackstands to make plenty of room for work. My Miata didn't have spring loaded bolts, and I've never seen them on any of the cars I've worked on... any special socket size I need to worry about?
