i have a gm performance exhaust on my ss/sc and my the tip of my exhaust rattles on the bumper anybody know a fix for this

 

Are your hangers loose at all?

 

if your hangers are on properly it shouldnt hit the bumper but if it still does for some reason you could put some kind of rubber or materal that will keep the metal from hitting the bumper on it so it doesnt rattle...even a piece of thin stick on weather stripping you can get from any local auto store (auto zone, advanced, etc...)

 

Maybe your hanger broke off your exhaust...I cant see why else it would be hitting your bumpber.

 

the hangers are all in place

 

Is your bumper in place then?
