Ok this is really starting to **** me off to the point where Im about to take them off & put my stock manifolds back on.. Every since I installed my cam the Driverside header is Banging on something.. I've tried everything i have a piece of 1/4 in High temp rubber between header & the k-member right now & its still banging the hell out of something. Also have a piece between ORY and my floorboard & its still doing it.. It kinda seems like it got worse to be honest.. Where could it be hitting & how do I fix this. Its fine as long as I have my cut out off (I guess no back pressure) As soon as i put the plate back on it sounds horrible & it Embarrassing when your at a drive through or red light. So please help..

 

more than likely it's the y-pipe banging on the floorboard. Probably needs to be adjusted.

 

If its the K member, you can grind it down some. Good luck
