Which exhaust gives the best gains?

I was thinking about gmpp which it advertise about 12hp.

How about magnaflow?

 

dude, i'm going to save you a lotof flame here.

there are 544354345 threads on this, but honestly, it's all about preference. i don't think one is going to give you a huge boost over another.

 

Most are around the same. With a 3inch you might LOSE some power unless you have other mods to support it. Keep that in mind.

 

the search button works just fine, but since i would have done the same thing...all of the exhausts will net about the same. you are mostly doing it for sound as you wont feel a big difference. i have the gmpp touring personally, if you want vids search my name and a thread should pop up.

 

I thought the Corsa Sport had the best overall #'s?

 

I believe that on an SS/SC and not a 2.2L

Will be closer to 6hp on a 2.2.

 

Delete the word BEST from your vocabulary.

 

When he says "BEST" doesn't that mean to most people, the most expensive?

 

best is 9 times outta 10 the most expensive and you will usually see the most performance outta of it too.. when you buy the most expensive then its usually a reputable company that has designed there product and tested it for performance.. thats not always the case but it is most of the time.. and if nothin else its more quality built than most others.. bein your doin it on a 2.2 then like said before its mostly for sound cuz you wont really feel a difference.. so its basically what kinda sound your goin for..

 

gmpp performance exhaust..... see if CED has any of the 375$ stock left? its basically a brola with gmpp tags....correct me if i'm wrong.

 

the gmpp is made by gm, so you know damn well its made for our car. I would say that it could give the best gains...

 

lawl...pacesetter FTW...

 

on the ss/sc....there are dyno sheets of a 16hp gain using the ARK DT-S catback.....not sure if it was coupled with anything else though......u'll have to search that one......either way gains aren't really noticeable until you have full exhaust then in the upper rpm's you'll notice a change..........

 

just get a gmpp. you will probably see around the same gains with all the exhausts but the gmpp wont cost much and you know it was made for your car. plus cops can give you a noise violation ticket.

 

no...the gmpp is more like the corsa, the corsa is also backed by gm so you dont have to worry about warranty crap

 

Pacesetter IMO sucks ass and isn't that big of a deal. Megan or Ark is where it's at.

 

dude i was in the same boat as you looking for the "best" exhaust. but really, they're pretty much all the same crap. the biggest difference between the exhausts would probably be the sound. you must realize that even tho the advertised gains may be different, most of them arent tested under the same conditions. for example, some are estimated gains and not actual gains measured on a dyno. and some are (well most) are tested on the ss/sc to show higher gains since its a forced induction engine.

just go by how much you want to spend and which tip you like i guess. i would personally recommend the gmpp one because of its good price and the fact that it keeps the warranty intact. Im going to buy the vibrant one because i also want the vibrant header/downpipe so its my best guess that they work well with each other.

Just my 2cents, hope this helps and happy modding

 

vibrant.. proven most horsepower gains

 

GMPP was installed on a California '06 LS w/SAI on Redline TV and dyno showed 8 HP increase, then they installed an Injen short intake and got another 7 HP for a total of 15 HP at the wheels. What they didn't show was what they did with the SAI hose -- you can see the guy holding the hose during the intake install but he just let it go

 

Whatever you do.. do your FULL EXHAUST... DP Cat Headers all that good stuff
