Well worth the money
I was skeptical at first because of the straight through design, but the muffler really quieted down my truck at idle and while driving

6.0 powerstroke sounds great!
Perfect fit for my straight piped 6.0 powerstroke. Still just as loud but took away the annoying drone at 2500rpm. Sounds great!

Worth the money
I put this on my bumper exit and I thought it was going to do really nothing but it cut down the noise a lot
