Our patented spin-trap muffler design has gone low-profile with maximum performance.  This muffler is only 3" thick, yet can accommodate up to a 3" inlet/outlet tube!  On top of that, it flows at 100%!  That's right, this muffler flows as well as a piece of straight pipe of the same size as the inlet/outlet tube, and we've got the flow-bench results to prove it.

This muffler produces an extremely smooth, deep tone without sacrificing ANY performance.

Available with inlets/outlets in 2.5" or 3", or a combination of 3" inlet / 2.5" outlet.

Dimensions: 18" x 7 1/2" x 3"
