I have Edelbrock TES headers, 3in cat, and Flowmaster 3in cat-back with 3in stainless tips. Let me tell you that it sounds freakin awesome because I have a pretty healthy motor. My problem is I keep blowing out the Fel-Pro donut gaskets between the headers and Y-pipe. They blow out within a month and it really pisses me off because I have to keep changing them cause it sounds like ****. Any suggestions?
