This 2004 24v Cummins Common Rail diesel sounds insanely good with this 6″ Cat Stack setup. Made by the guys over at SoFlo Diesel, you can get your hands on a set like this for just under $500. This specific kit is the side by side 6″ Cat stack, including the 41″ tall satin black model with the 5′ inlet. This 24v is rocking a 5″ turbo back exhaust and a Smarty S-06 for the tuning. The camera audio srtuggles a bit for the in-bed portion, but there are plenty of other great sounds clips to be heard. Turn those speakers up! (video below)
