is the exhaust mounting etc the same for 01-07 if you do a turbo back system. I have been looking at a lot of places for one for a buddy with and 06 ext cab and I can't really get any good answers

it might be different from the 01 to the 07. i dont know because all i have is an 07 classic.

You can use the same system on pretty much all the trucks before the LMM. The LBZ doesn't have the 4 bolt flange that the LB7 and LLY have. I am almost 100% sure on this. There is a MBRP vendor on this forum that could give you first hand knowledge.

I just installed the silverline 4" turbo back last week and the box was marked 01-07 on it mine is an 06 and everything fit extremely well
