i have seen them, i know they exist. iam looking for nerf bars that have side pipes built in for the exhaust. at the time i had a 2 wheel drive so i wasnt going to use them, now i have a 4x4 i cant find them. has anyone seen them?

 

There is a small time exhaust shop here in Podunk, Nebraska that advertises them, so I went down to check it out. He told me the largest diameter pipe he could do was 2.5" or 3.0" (can't remember). The exhaust pipe is covered with like an inch or so of ceramic or something similar to absorb the heat. Then the ceramic covered exhaust pipe is put inside the nerf bar. I told him I wanted a 4" exhaust pipe and he kind of laughed and said that would make the nerf bar about 6" in diameter, which is a little big, I suppose. Then he said going to a 4" exhaust wouldn't do anything for a PSD anyway. That was when the conversation ended. Just my experience with them.

 

thanks for the reply, ive seen them advertised lately and i dont remember the size but i dont believe i would want just three inches
