lol yes im keeping the header i have like 14 hours of labor putting that bad boy on unless someone were to offer me a ridiculous price for it, if we can meet i would let it go for 160, its 235 brand new and its stainless so will last forever

the stock dp is pretty restrictive, there's a few areas where it looks like it didn't fit so they banged it in with a hammer, also the cat is pretty restrictive. but you're probably not going to lose much more power than you already are with the gmpp exhaust.

The stock DP has a 2 inch restriction at the flex pipe, so i'd guess 5-7 WHP.

anyone have an idea how much it would cost me for a new flex pipe? also, how hard is it to change it?

my exhaust is making a lot of noise now and its unbearable. i was told by my brothers and some people here that it could be the flex pipe. i can't afford to go to a shop, so im hoping to change it myself. any ideas?
