I like the GM exhaust!

 

Magnaflow sounds really good, i have there exhaust on all my cars

 

Ive heard a lot of good things about the GMPP exhaust and I guess its only about 350$.
Borla Muffler on it? Get the TOURING or its too loud. Or the Corsa touring exhaust.

 

The GM or magnaflow are the overwhelming favorites by css.net members

 

Gmpp By Far Bro! Easy Install And Sounds Great.

 

Out of all the exhausts I've heard for this car, CORSA Touring, hands down!

 

how much hp does the gmpp one give?

 

Have Not Gotten Dyno Done... Getting Gm Stage Ii Installed Tomorrow

No doubt.

 

So how hard is it to install a header do u have to pull the motor out?
