OK so I went with the 2.5inch. A BBK catted H and flowmaster cat back with super 44's on it. All came to my door in a week
As for the headers, I pulled them off the car because I could hear a leak and found that it was leaking at the head on two of the primaries. They looked to be in great shape though so I decided to get new gaskets and keep the stock manifolds. Just going to paint them up and put them back on. Cant wait to hear how it all sounds, I'll report back..
Any recommendations for painting the OEM headers?
