For my birthday from my great wife, I got 4" exhaust (straight pipe) from the resonator back with a turn down chrome tip. It sounds soooo sweet and is not loud at all
I was driving around this evening with the beer can window open just hearing the music of the Cummins and the turbo spooling down. I also took wife for a ride to convince her it wouldn't be any louder than the stock muffler on long trips:-laf
