I recently installed my exhaust system on. It has this rattling noise coming from the bottom. I think its the little extension things that goes onto the rubber boots to hold them up is touching the frame of the truck. Any suggestinos on how to get that rattling to stop???

 

if i get you right, your saying the support bars for the exhaust system which are normally isolated from the frame by the rubber connectors are now touching the frame? a pic would be super helpful. if that is the case, i would just try and do whats necessary to keep it from touching, like shortening or bending it.
