I got the Performance one, not the touring.
Outside temps were identical. Low 70’s.
Tom has a special on these. Hit him up, he'll take care of you:

Can the exhaust tip from the stock fit the new performance exhaust? It would save $50

 

hey johnyyB... is that the 60 dollar exhaust tip from gmpp? or is that one froma local autozone or murrys? thanks man

 

nice nice NICE!!!!!!!!!!!

 

Yes, It is the tip from GMPP.

 

does anyone know where i can get an avi player so i can hear how it sounds? my windows media player cant play it and quicktime is givin me an error when i go to play it and yes i saved it..darn i wanna hear it lol

 

congrats nice gain!

 

Nice numbers..I can't wait till they get the kits set up for the 07's ...just got my silver one on fri with the g85 package...Loving it sooo far...

 

i really like your tag, great gains too

 

Hi there,
Nice HP gains, I was wondering if you could be more specific at to which exhaust you are refering to:
A. Cobalt Cat-Back Exhaust System Performance 17802111 $357
B. Cobalt Corsa SS 2.0L Sport System 14128 $679

I want to get one....just want to make sure I get the right one

thanks

 

He's talking about this one.

A. Cobalt Cat-Back Exhaust System Performance 17802111 $357

 

wow, thats a big gain for a small amount of $$$$

does anyone know the HP gain difference between the Performance exhaust vs. the Corsa SS?

I don't think I want to spend the $$$$ for the corsa SS unless the HP gain differnce is substantial, I'd go stage 2 instead for those $$$$

thanks

 

I just passed 1000 miles on my car. Haven't even looked under it yet. What is the black box over the axle ?

 

Our results on the Redline were nearly identical, I believe it was 11/11 when it was tested, so sounds pretty legit...

 

the black box looks like fuel pump/ fuel recirculation..... correct>?

 

I believe that's the BCM...

 

12 HP gain! Sounds like that's what I will get for $357! Hopefully, it will be even cheaper in March-April time frame.

 

damn those are good #'s

 

great stuff yo ... question though ... my exhaust having been installed a few weeks seems to be resting on the left side (drivers side) of the exhaust position and I don't know why ... when I installed mine it seemed correct but for some reason it it resting nearly on the car ... anyone know what I can do to correct it? from your pics it would seem that you wont have this issue though I didnt have it either at first ... should I get another paid of rubber mounts?

 

I went from 220whp and 186wtq, on my stock dyno, to 231.7whp and 198.xxwtq by adding the Typhoon CAI and the GMPP Perf. Exhaust to my car. So I believe this guy. Love the exhaust too, nice and deep tone.

 

looks nice and congrats car looks clean

 

yep, don't think it's the pump but something with for recirculation
CTCOBALTSSS is correct. If you ask me, Corsa is a bit overpriced. Buy GMPP and use the rest of the money for other mods But that's just me. Your car, your $

Thank you,

 

Price and gains pretty much says it, GM catback for all I love mine

 

I really worry about limiting myself with a 2.25" exhaust... but the price is so damn attractive and I can just go pick it up from the place...

 

it's about flow rate man. plain and simple the gmpp flows a helluva lot better than people give it credit for.
