I have the Performance and like it alot, but I'm swapping the actual muffler out with a different one soon. I believe mine might be slightly blown as it's quite loud and airy now.. But it's a high-mileage system..

Actually a 2.5 inch system is fine for an n/a car. You don't need 3 unless you're boosted.
I would get the GMPP and see if you like how it sounds as-is. If you think it's ok, weld on the Magnaflow and sell the GMPP muffler. lol

than from your sig u already have a magnagflow exhaust, did u get the 2.2 or ss version? the 2.2 is a 2.25" which is tiny, the ss version is 2.5 in which swapping to a gmpp would be a downgrade, if anything i say get a 2.4 manifold, will give you more hp/$ than the exhaust will, than go with a 2,4 TB, header/dp, and you'll be set...

I noticed a big improvement with my ZZP header/dp combo when I had it. Agreed. 2.4 manifold, header/dp combo and you'll be good. But honestly, how good of a deal are we talking here on the GMPP? lol If it's like 100, you'd be dumb not to.

I paid 400 for mine installed. 200 is a legit deal. Super easy install. A few bolts. I'll make your life easier if you have some type of Sawz-All to hack the stock tubing. worst case scenario: use the Magnaflow muffler still. That's what I'm doing.. Getting an HKS muffler (or something like that) and just replacing the muffler on it..
