u will definately not be sorry with the Corsa. They only thing that turned me off about the GMPP exhaust was that is was 2.25" piping.. why? when the rest of it is 2.5" kind of restrictive especially if u plan on modding the car and putting a smaller pulley on

 

Called my dealership for pricing on the GMPP sports exhaust and its 610$ I went on GM parts direct and put the part number from the first page and it gave me the muffler tip only. Anyone have the part number for this? All I want to do is buy one! I Hate shopping!

 

I second the Corsa! Just installed mine today and its AWESOME!

 

So the GM catback is 2.25, isnt that the stock diameter?

I dont see shelling out $500 for 5HP lol

 

You're going to get about 5hp w/ any exhaust you get.

 

AWESOME!

lol ill stick to stock

 

i thought that it would be a bigger gain in hp with an exhaust system. about a 5hp gain is that with a catback and a full exhaust?

Mods:
AEM intake
Future mods: stage 2, ingalls engine damper

 

No, you get more than 5 hp. I can garentee that, larger piping and a free flowing muffler is going to be closer to 10 hp. When I got the magnaflow, my torque steer got so bad it was scary, 5 extra hp wouldn't do that.

 

this is probably a really bad question but what do u mean by torque steer ?

 

the car jerks real hard in one direction when you give it gas and is amplified at lower speeds when a sudden acceleration from the driver is initiated

 

as a note to the hp with exhausts, i think it is measured as percentages rather than mechanical power. The increased flow is where the power is coming from. The more power you add to the car the quicker exhaust gases are created which means if there is less restriction the gases can get out faster which in turn increases power. It was mentioned that a 2.5" exhaust will perform much better than that of a 3" exhaust if the flow rate of the 2.5 was higher. Diameter plays a role but total flow of the heated gases will ultimately lead to better performance.

edit: that being said, while a few hp over stock may not seem much the overall result will be better as mods are added to increase mechanical hp since the performance exhuast would be less restrictive than stock

 

which exhaust do you think would look best on the base model 2.2l cobalt...without the lip...i ???

 

corsa all the way just got ordered mine to day around 670 shipped JEGS.com check it out

 

Is there any sound clips yet? I havent seen any.

 

has anyone heard the dc exhaust yet???

 

Yah it sounds pretty mean, i only think it has gains of like 4hp though.

 

No one exhaust is really going to give you more horsepower than the other.

4-5hp, if you are lucky, is all you will really get out of a catback exhaust on these cars.

 

Does anyone know if that magnaflow exhaust for the ss 2.0l will fit under the car for the 2.2l sedan model? I'd rather have the full 2.5" piping. Thanks

 

Yes, piping path is the same as far as I know for the 2.2, 2.4, and 2.0

 

long over due ... here is a comparison of a GM performance exhaust and a stock exhuast.

In the original videos of the corsa exhausts, is that the touring or the sport one?
