I have dual exhaust coming out my rollpan, 3" tips, and it rattles like no other, i had door edging stuff around the holes, it helped a little, but that stuff gets heated up and its hard as a rock. Can ANYONE tell me what i can put around the holes, that is maybe soft and heat resist that i can bend and twist and stuff good, and where i can get it!!!! it would be highly appreciated. THANK YOU!!!
