Hi all am am getting a really bad rattle when starting and cutting the engine which I think is down to the exhaust I've changed 1 of the rubber mounts which had totally given way the D shaped 1 but fort I should have jus changed them all, but havin trouble getting hold off the right ones. I got the D shape from main dealers I really don't wanna have to go again can anyone point me in the wright direction. I find it hard to believe a exhaust rubber is a main dealer job but not even GSF stock it
