So Im planning on exhaust in the next month, and I was looking at either a corsa sport system or the magnaflow system, however, over the past 2 weeks, both cobalts that I have come across in london, both have the GMAC catback system... I didnt get to hear it in either case, but would this be similar to the exhaust that I would get with corsa/magnaflow? Just different sounding, but performance wise, around the same thing?

Anyone with this or opinions please post!, thanks.

 

I heard both the magnaflow and mine the GMMP catback and they sound simular,theres no difference in performance.I guess it comes down to which one you get cheaper my GMMP catback was 428.00 through the dealer.

 

it's GMPP, not GMAC.. but i understood.

I have the GMPP and I love it.

 

Magnaflow =

 

2.5 in piping + Apexi muffler =

 

Magnaflow > 2.5 in piping + Apexi muffler. jk
Go with what you think sounds best

 

It's all personal preference man I'd suggest getting piping built and trying different mufflers until you find the sound you're after. You should be able to go through about 4 or 5 mufflers before you pay the amount a shipped exhaust runs.

 

Ha yeah! After my flowmaster and piping was done, it was $103 after tax for the magnaflow.

 

ah so looking at performance, theres no diff.. That was my major concern, but thanks!

Ill probably be ordering the GMPP since I can get it through the dealer, thanks for information everyone!

 

Glad to help!

 

I'd go w/ Corsa because I love the sound. That is if you don't mind spending an extra $250 or so.

 

Ok so ive decided to stick with the GMPP catback exhaust, now I have another question.

I went to my dealer today to ask how much it was to have the parts ordered+install.

They have 2 tips, the flat and like angle one, but the flag tip that they have doesn't have the chev symbol at the top, and the other like 3 people's catbacks all have it, is it the same? Cause id rather have it with the chev symbol like everyone else.

The part #s i got were 17802113 for the tip, and 17802111 for the actual exhaust..

Anyone have any information and if this is ordered right from GM shouldn't mine be the same as everyone elses? Thanks for information.

 

Cobalt Exhaust Tip Straight Cut... 17802113
Cobalt Exhaust Tip Angle Cut... 17802112

Those are the two I got, so far though everyone ive seen with the GMPP exhaust has the chev tipped straight cut I believe and id like mine to have that as well.

Any help would be awesome, thanks.

 

help meh please! lol

 

bump again, still looking for answers?
