Nelson or Donaldson 5" STRAIGHT THROUGH muffler??
Glad it was helpful. I have since gone back to the stock piping with a Silent Might Rokktech muffler. After I upgraded the stock turbo to a silver 62, the drone was a bit more than I wanted so I tried the Silent Might and it worked very well. Still droned a bit with the silver 62 but not as bad as the 5" system.
A Nelson 86131M (86130M in 5") is a 4", straight through 51" muffler with no baffle. I'm running this with a cat on my SB and it has no drone. The exhaust note is only slightly louder than stock. Amazon carries this muffler, although I bought mine at a truck repair shop.
