Just a tip request. If a 3/4" width "c" shaped ring was included with the universal and was advertised as a spacer for odd diameter exhaust pipes, it should increase SuperTrapp acceptance.
I'm fabricating my own spacer ring to seal the gap between my 2 3/8" OD exhaust pipe and my second 2 1/2" ID universal SuperTrapp installation.* I could just crimp the universal's inlet down like I did before, but I like the spacer idea better.
I think others would find this a welcome convenience too.
* Second installation, because I have a second bike. Just wanted to clarify that my thoroughbred ZX-9r isn't going anywhere.
