It is less than 2.25". There is a kink in the dp that brings the diameter down.

hmm, ok, I am going to assume that is reason I am running slightly higher than normal times with my car.

definitely. Your ported mani's haven't done much for you huh?? its because you need a new dp with them. Get at least a 2.5" dp.

well, I see no KR with 3.25. I am going to go with a 3" DP. Hopefully I can get one in before IDD.

RTDP have a 3'' DP.............Its the U bend that the real killer though.

Have Jim give you a 3" DP and U bend deletion, OR, you can buy a prefabed on like from RTDP and have a 3"DP, Ubend deleted, Hi flocat and you choice of a 2.5 or 3'' to your cat back exhaust.
