Unfortunately, the Triumph cruisers aren't very well represented over here so you're pretty much limited to debaffling the stock pipes, TORS or something custom-made.

I think most of the UK riders that frequent this forum have TORS and they're fine; I've never had any undue attention from those in blue. (Not for the pipes, at least!!! )

My mate rides round on a bright-yellow, custom Hog with straight-thru drag pipes and he's never had a problem. (He's also got a wholly-illegal, 3"x2" black-and-white no. plate.) He's either very lucky or cops aren't too fussed about cruisers.)

If you want to debaffle the stock pipes, do a search for 'bafflectomy'. If you want to go the custom-pipe route, it needn't be as expensive as you may think.

Nice retort, by the way.
