I already have the can, a Fuel one, got from eBay for £50, and I also have some Motad downpipes which have the stop on them, I just wanted to fit the can first, so dozy commuters stand more of a chance of realising I'm there, and fit the downpipes just before the MoT next year (cos I'm tight) I just wondered if anyone had come up with a genius idea for a stop.
