A couple of quick questions... I'm thinking of purchasing a Yoshimura S/S slip-on for my GS500FK9 (found a new one for $USD300 with $USD25 shipping on eBay). My questions are as follows: As I am on my P's for another 10 months, would this cause a problem with the RTA/police? (ie. move the bike outside the LAMs classification - and yes, I know that if it too loud, I'll attract the eye of the police), plus If/when I need to get the bike inspected for rego, should the bike pass without changing back to the standard pipe? You can assume that I'll have the noise insert fitted.
