anyone know who does them? On my system, I can use the 3 bolt triangular gasket from a Beemer (47mm bore, 60mm c to c for the bolts) but I'm struggling to find 2 bolt gaskets, other than stock...(58mm c to c)....someone must've been here and done that.... I've seen the slip in copper ones for 1 1/2 inch but I'll be buggered if I'm going to pay £30 for four gaskets.... BMW 316 fits collector to silencer for 38mm pipes (on mine atleast)
