Is there an aftermarket 4" turbo back exhaust taht looks like the factory exhaust? I want my truck to maintain a stock look.

I think my MBRP exhaust looked stock without the 5" tip. I actually cut the tailpipe shorter for the tip to fit correctly.

any aftermarket exhaust can look stock, if you don't use a tip... the only thing that will be different is the shape of the muffler and the bigger diameter of the 4" exhaust.
