Abz Posted May 29, 2012 Share Posted May 29, 2012 Ideally after an RSR Exhaust bung (mine came out on the A13 and after a good search it seems to have disappeared into thin air!). Either that or something like a butterfly value so then I can quieten it down for motorway travel & cold start. Let me know. Abz Link to comment Share on other sites More sharing options...
