I think the noise inevitable with an exhaust that has been constructed with 'safe' pewrformance in mind.
Those manufacturers that build a Clubman with a small tailpipe essentially compromise the engine in allowing heat build up. In fact, there is one 'Development' manufacturer that writes prolifically about their claims on websites, including how long & how many development exhausts have culminated in their all-singing, all-dancing Clubman. It might be Roman as it has a V in it.....Anyway, whether it is made by Romans or Lizards from another planet, the tailpipe is too small for any well set-up tuned engine that needs to get rid of waste gases without a physical restriction to doing so.
I don't think a VW Beetle type muffler will last &, in any case, they are also restrictive.
Wouldn't it be nice if you could find a two stroke silencer in kit form within the UK, sourced from an auction site for about 15 quid? That way, you could shorten one to suit what you have prior to packing & assembling!
(PM me if I haven't given you enough clues to find 'em!)
