The previous owner had drilled some small holes through the capping plates on the mufflers. They weren’t very symmetrical so I enlarged them but they still looked crappy.
I had some end caps made at Redline Exhausts.
Muffler with no cap…10mm holes drilled.
Stainless screws & spacer washers.
End result RHS…
It’s almost too noisy for my pillions. Fine with ear plugs of course!
