There are tons of opinions on this subject on the Diesel Place (tends to favor GM). The general conclusion is the greatest benefit is in the area of the muffler. A "straight pipe" style muffler reduces back pressure by about 15% versus entire exhaust pipe and muffler changeout achieving 16%. Also, the general consensus is a goodly decrease in EGT (which can only be good) from any breathing improvement..
