Are the muffler and headers worth buying from GM? If they are at least decent how do they compare to say Gibson or Magnaflow?

i have the GMPP sport exhaust. but im scared about putting it on my car because it may be a waste on money. from what i hear. sounds pretty good but not much performance gains. but in all. id rather sound good

carbombss

I have had my gmpp sport exhaust on like 3 months now and u will notice a power change at mid range rpms and also does sound really good

c7015

you would rather it sound good an offer relativly no gain in power ... ?? why spend money on sound?

Im trying to stay geared toward performance, but im stuck all the exhaust besides the GMPP sound farty to me.

GT_Desperado

The Magnaflow doesn't sound that farty.

celicacobalt

corsa has no farts at all

R33P3R007

its a 4cyl... they all sound farty to an extent. they are missing 4 cylinders.

Ghalterman_usmc

I agree with that guy^^^^^^

OniMirage

imo the corsa has thus far sounded to most farty of the bunch with the borla magnaflow and gmpp following in that order

IonNinja

keep it quiet and you'll have less worries

don't buy a system without a resonator or no rear muffler...

scotty1979

p7x

Wow, I like the GMPP exhaust a lot.

distillion

i wanna know the actual gains from the GM exhaust system

p7x

same here Im really curious unfortunately, this might be an instance where performance might take a hit to have a good sounding exhaust.

distillion

agreed, it sounds good, and even if it helps out wtih hp and torque by just an ass hair i will buy it

Ern

U gotta be kiddin me!!!

The only one j/k (sport/performance) look on GMPP website

It's the performance exhaust and u meant "touring"

i love when people say the magnaflow doesnt sound farty because i think they have an obscured view of what farty is unless you like that which is fine. I am just saying i went with borla because if you want the least amount of ricey-ness(2.25 inch diameter) with descent performance gains(not sure what they exactly are) and plus borla just makes the best exhausts for the money. Wouldnt put anything else on any car.

Cat-Back Exhaust System - Performance
17802111
$489.00


Cat-Back Exhaust System - Touring
17802110
$589.00

These are from the GMPP site. They are both for the cobalt but didnt list what engine size they were for. Might be made for all but who knows until I or someone else talks to a parts personel at a Chevy dealer.

Doc

its the performance exhaust, 17802111
I'll dyno it sometime soon hopefully this week.
The exhaust is for a 2.0 or 2.2.

there are 2 exhausts, performance (17802111) or touring (17802110)

hardtocope

whats the difference between the performance and the touring exhaust from gmpp? would the performance exhaust be able to pass inspection in new york state or is to loud?
