I'm getting tired of replacing my driver's side header collector gasket once a month. I've been using standard 2.5" I.D. (actually 17/32") donuts. The problem is that they keep blowing out the
composite material between the steel windings. The y-pipe is lined up. The bolts are keeping enough pressure on it, but they continue to blow. I know someone makes a solid donut gasket, but the dummies at the parts store can't look anything up without a reference in the computer Can someone tell me who makes them and where to get them. Part numbers would help the idiots behind the counter
