hey guys.. i need yall's expert opinion on the best exaust system for our 8's.....

HKS Legamax

Greddy SP2

Borla

OBX

Tanabe SMH

wich is the better choice.. and i kno i've missed some too!

 

i like my borla... which is the best i dont know

 

HKS is the best sounding in my opinion.

no idea what performance difference these give, if any.

 

None of the exhausts are gonna give you much gain, it's your midpipe that will yield more hp. My recommendation is to get the RP Supercat and then whatever exhaust you personally like.

A good place to start.

 

IMO that is a terrible link! Especially at the beginning where all the companies were claiming ridiculous hp gains. Anyone who has dyno'd thier 8 with one of these exhausts will tell you otherwise.

 

Look in the aftermarket section, there are like 5 threads going on right now.

 

It gives photos, and in some cases links to sound clips. Given the power debate about these various exhaust systems, looks and soud will mean a lot. Through all 11 pages, there is probably some information he can pick up here and there to help his decision.

And RB may have claimed 8hp from a full catless exhaust, but Rotary Performance and TurboXS (with a forum member as witness) observed a ~20hp gain from a midpipe and cat back. Whoever you choose to believe is your opinion, but both sides are reputable enough to throw weight to the argument.

 

Thats why I told him to go with the RP Supercat in my earlier post. Its not the exhaust giving that ~20 hp gain... its the midpipe.

edit: and its not my opinion, its been proven through multiple dyno's from owners including myself.

 

In terms of just a cat back system, I agree with what you're saying, little hp to be gained there - which was my point with the photos and sound clips.

And I didn't fully read your earlier post regarding getting the RP cat with a cat back. I think that so much is the way to go, that that is the way I went with my own car. I had the RP cat and felt a slight pull in the high rpms, a year later I added a cat back (Tanabe) and felt zero increase in power.

 

Helix would be my favorite exhaust except it never went past the prototype stage. One of the member here have it and posted a sound clip. It sounds very exotic and a little V10 rumble. The only complaint I have with it is the way it is designed. It dips very low to avoid the rear diff and it looks like it will scrape on the littlest bump.

 

As low as it is, I don't think its ever scraped.

 

none of those mentioned are a full exhaust which is asked for in the thread title.

 

thanks guys all that sounds good.... ok now how about the best combination on the best catback and midpipe on this site http://www.rx7store.net/category_s/122.htm

 

...The only "full exhaust" I know if is made by RE Amemiya, with their header, midpipe, and dolpin-tip catback. So..that would make that the ONLY option.


IMO (which is limited at the moment), RP Super-cat, Mazdaspeed Sport Catback.

 

yep ther ya go the best full one rigththere- because its the only complete one

 

the man is right!

 

yea i think i'ma go.... agency power titanium exhaust and rotary performance midpipe... whats a good header? can't seem to find 1 except on ebay and it's OBX but i nunno.. and does the midpipe alwayz trip your check ingen light thats wat i heard

 

wait a few months for racing beats header to come out. then there will actually be a choice of headers

 

Cmon... TurboXS is the best, so far.

 

I like the search button exhaust... but for sound RB

 

Any estimates of gains?

 

wut about abflugs exhaust? ne1 here know how it sounds like? and how much hp/trq it puts out? and go here

http://www.rotaryextreme.com/rx8index.html

theres a few choices of headers there

 

aight 4 sho... i'll prolly wait for that... any idea for price range?

 

FEED also makes a header for the 8, just FYI... a bit pricey though, last I saw it was 1300...
