Nerf bar/Side Pipe Exhaust
We have a new custom exhaust guy in town who is advertising a nerf bar/side pipe dual exhaust. I told him I wanted 4" straight pipe and he told me that with the pipes that short that all his new exhaust info says you lose performance. The pipes would actually end somewhere behind the cab. He suggested staying with the stock 3.5". Anyone heard of this?

Uhhh - obviously that guys knows diddly squat about turbo-diesels. You do NOT need any kind of back pressure - your turbo gives you all that you need. Go ahead and open'er up to 5" if you like!
