There’s an article in the April 2013 issue of airheads’ Airmail regarding deleting the muffler and installing an exhaust pipe tip off the center resonator (R100R/GS), which recommends the 7” Superior Automotive p/n 28-2151 available at Pep Boys, etc.
I’ve heard this and can report it isn’t objectionable at all. Surely not as good as the Rooney unit but works in a pinch and beats the price of an aftermarket silencer.
