not bad man, im gonna get the gmpp, what tip are u using for the muffler?

 

17802112 - angled tip - $67.91 shipped from gmpartsdirect.com

 

i thought that was the part number for the actual cat back??

 

no, the cat-back is 17802110 or 17802111

 

oh wait the sport cat back is 17802111, my bad.

 

17802112 = angled
17802113 = straight

 

uhhh im keeping mine now . this is what i have been waiting for is a video.

 

Well people we are really starting to get together a nice database of information on the exhaust packages. Thanks again to all the contributors, really helps those of us who have yet to purchase one.

Thanks to Doc for his newest videos of the GMPP Sport exhaust.

Corsa no longer has a firm lead in the voting, and only had a 4 vote lead over magnaflow when i last checked this. GMPP is slowly gaining votes after Docs new videos.

 

I believe we've determined the GMPP was Borla. Who was it that posted that it said Borla on the instruction sheets?

 

on a base cobalt with no ground effects do you think the straight tip or the angled tip would look better? also will the gmpp exhaust sound the same on the 2.2 cobalt as well?

 

it does say borla on the bottom of the Instructions. Appearance wise. its a damn good looking muffler. its for GM Performance Parts in the metal on the resonator and muffler. looks cool.

 

it is a borla!

 

i think i will be going the gmpp cat-back for my car, sounds nice and is backed by gm

 

Is the 2.25in Piping going to limit us to yield the most power that we can get out of an exhaust? Wouldn't we want 2.5-3.0 inch

 

Hey Doc. Was the second dyno with the GMPP header as well?

 

Get the exhaust on ebay. It is only $379 and I am sure they take paypal.

 

no, it was with the Injen CAI

 

Has anyone removed there cat yet? If i were to remove my cat and install the Magnaflow exhaust system, what should i take into consideration? Will i throw an CEL's or will i need to get a o2 Simulator. Not saying I'm going to do it, but just something that came to mind.

 

you can gut your cat or use an o2 simulator gutting it will be cheaper of course.

 

i have a question. my car is on the smartbuy (lease) and i'm going to be trading her in 3 years. i really would like to purchase the gmpp exhaust and install it but do you think the dealer would me crap about it when i'm turning the car in?

 

you can unbolt it. You'll have to save the old exhaust if your serious about returning it to stock.

 

well the stock exhaust has to be cut off.

 

jus got the corsa installed today and that was the best thing ive done so far. really wakes the car up it will go 30-90 like nothing. even faster than before. and the sound is amazing. i really love the way it sounds and it was everything i was looking for. IT POPS WHEN YOU DOWN SHIFT

 

I hate exhausts that do that. Saw/heard an SRT4 with a Corsa at a track event with an exhaust that did that and it sounded like ass.

 

They are all going to do that, the stock even does it, you won't be able to avoid it.
