GMPP Performance Cat-Back
So I finally ordered my GMPP, I work at the dealer so it cost me $500.00 with tip. It gets installed on Saturday, I hope I will be impressed.
What are all of your first impressions with this?
Gains? Boost? Feel? Sound?
Nobody has a GMPP Cat-Back?

I've had both , they both sound good , if your looking for a performance increase , you prolly won't feel any difference . The Performance will spit and pop on downshifts , and you won't hear the blower nearly as much as u used to . Boost will stay the same or go down slightly . Touring is the same only it's mellow and only loud when you mash on it ..... oh and you can still hear the blower .

i noticed very little power gain after i added on my gmpp header and catback w/ the touring tip. i love the sound from the touring because its noticable but not obnoxious. after i put on my k&n intake i felt the car opened up quite a bit. i think if you going with a catback you should compliment it with an intake to open both sides of the air flow.good luck on the install
