I have a stock H pipe from my 08 Bullitt. I'm not local but if nothing works out let me know. Also remember that the Bullitts came with a slightly different, how I do not know, H pipe to help with the sound.
Theres a "washer" in the middle of the bullitt h pipe with i think a 3/8 hole rather than being completely open.
I dont have to have a bullitt specific h pipe, I'm just looking for one so i can gut the cats just in case i ever get pulled over by the cops here in CA. i dont wanna get towed.
