Underbody Rattle

[codycourtney2@yahoo.com]

I installed the MBRP exhaust and the lift shortly after, and now i have a rattle underneath. It is definatly a metal on metal hitting. When I hit a bump, even a small one, something underneath hits. It sounds like something heavy, maybe an exhaust pipe hitting the frame. Its not a fast rattle, just hits once or twice on a bump or something. Sounds like its under the center or the rear, but i cannot pinpoint it over the sound of the engine. Has anyone had any similar problems? Has anyone had any problem with a rattle after installing an exhaust system?

I have the same rattle. Check the heat shield above the intermediate pipe.

is it hitting where it goes over the rear axle?
