currently using a kirban 3" downpipe. Fits the stock elbow horribly. Does anyone make a gasket of some sort? Was told by kirban to seal with high temp permatex which lasted about 10 miles. I've also heard that a downpipe can cause false knock. Is this due to poor fit, rattling, etc.? who makes the best downpipe for the money?
