Anyone have any problems with their factory 4 sealing where it meets the header? I cant seem to get a good seal with mine and I have tried just about everything. My sealant keeps burning off and I get an air leak then my bike starts backfireing and popping.

haven't had any probs and i'm not using any sealant on the head side, only using high temp on both ends of the mid pipe.
