This muffler came on my truck off the lot. It has about 55k miles on it, it is a turbo style muffler. Sounds good not raspy at all. It will fit in the stock muffler location with no modification. I took it off and replaced it with the Doug Thorley SS cat back.
Inlet is Flaired to receive 2 1/4 inch pipe and outlet is 2 1/4
