The exhaust sounds great and the intake is loud as hell. My GMPP exhaust ships Monday, can't wait to get it on. What were your gains performance wise?

 

Not Sure of the gains! Didnt Dyno Before>>> But Between the Intake & the exhaust went on at 2 different times & you Could Tell!

 

Good to hear that you can feel the difference though...now I'm a little more anxious to get the exhaust on.

 

yah cobalt addiction states that the GM exhaust is 2.25". IDK, i like my corsa though, i got a sound clip on the dyno, sounds loud as ****, when i get it on the computer ill post it.

 

corsa is your best bet, its stainless and wont rust out after 3 years, its also produces more gains and imo sounds better. You can find it for 600, shipped. Worth the extra money.

 

I have had the GMPP or Corsa delema for a while now. The GMPP always won because its cheaper and sounds good. But the Corsa Touring sounds good too and looks amazing but is really f-ing expensive.

In Canada we get raped for auto parts, the GMPP sport from the dealer out the door (taxes , everything) is $700 CAN just found the Corsa touring, the exhaust i have wanted for so long for $1000 CAN out the door.

Anyone have a cheaper price CAN for the Corsa? I have thought alot about ordering from the US cuz its so much cheaper but with exhausts, after shipping, taxes and duty it comes to about the same, give or take 50 bucks.

 

my dealer told me his retail suggested on the gmpp is $520 canadian
he said he would do it for me for $460 + install.

700 sounds pretty high

 

i hate my new dealer they suck ass.

 

I was quoted 435 on the gmpp exhaust im still looking for a good price on the corsa though
