Quiet mufflers

Oh, I forgot about this option which would simplify what I was describing above..

Quiet Walker muffler with (2) 2.5 inlets, (1) 3" outlet. Dang, I am seriously considering putting this on my duster (mild 360 this go-round). Only difference is I am running the exhaust tube under my rear end axle housing since I have seen this successfully done with 0 issue.

This muffler is fairly large..
