Which exhaust????

There is no need for back pressure on a turbo charged truck... the turbo is the back pressure, Thats what your drive pressure is.

The 5" will gain you nothing, but it will not hurt you in any way...

Love my MPRP system... If your in an area that salts the roads go for SS... If no the AL pipe will last longer then you will keep the truck...

MBRP is the way to go.

4" is what I'm going with. A local shop that a friend works at they said pretty much the same thing.
