Hello guys!

I've taken my MC21 out on a few track days and had a blast. I've now done the wire splice and am looking to put a set of after market silencers on for a different look-and to preserve the standard pristine silencers that are currently on the bike. I definitely want to retain the standard expansion chambers, so any silencers I purchase must be a bolt on fit. I DON"T wish to modify/cut the ends of my chambers to suit silencers that have a different PCD/bolt pattern.

I guess, and without wanting to start a debate, what would be a good GP style silencer for a motor in a MILD state of tune that will bolt directly up to my standard pipes?

The silencer needs to be readily available in 2017, as there are many makes that have come and gone, and unfortunately some of the web sites at present are clearly out of date.

Best Regards, Frank
