Ok I was wondering about the pitts muffler...so it's a JTec P-51...I'm just running the standard muffler on mine...
his jtec leaves about 1/2" space to cowl, and simple trim in back to get the 3:1 outlet/inlet...otoh, my tbm side-dump will require cowl surgery...sorry for getting off-topic...i'm outa here...ken
