I just found that Dynomax makes and exhaust kit for the GXP. its like 500 so a little cheaper than Magnaflow. I think ill be trying this kit out.
 


Good luck man, let me know how it sounds and any performance gains. I'm not sure if I want to buy a kit or fabricate my own yet :( I may just make it a single 3" pipe with no cat that has a high flow borla muffler mounted underneath the rear seats. Since duals "really" doesn't do anything for us. Also makes me sad.
 
Definitely looking at an exhaust myself. Would love to hear how the Dynomax works out for you if you do try it out. I looked at the magnaflow myself.
 
it should fit the cars are all the same, k & n said that about there air intakes too.

There site only has v6 listed where did you find the kit at?
 
I went to dynomax's webstie. I did see it on some website but i dont remeber now. The person i talked to said there exhaust was only like 2 and a quarter or 2 and a half inch. To small for me. I think im just goning to get a custom exhaust, with Cutouts, and try the Aero Turbine mufflers out. What does the Hogan downpipe do for the GXP cars.
 


one of my buddies has a 2009 impala ss and wants to get an exhaust for it, any ideas? he said flowmaster, but i heard that can actually hurt performance...
