Installed the mbrp at back exhaust on my 2011 2 door and have a clanging sound in the rear whenever I go over any bumps at moderate speed. Checked the clamps and everything is tight and in place. The rubber exhaust hangers look a little stretched. Anyone else experiencing this or know a fix?

 

I have the MBRP exhaust as well and when i installed mine, i also had a lift kit installed that included a rear sway bar drop bracket. The dropped sway bar was very close to hitting the inlet pipe to the muffler and made clanking noises. I just took off the drop bracket and problem solved, maybe your problem is similar?

 

No, it has the stock suspension on it. The noise sounds like the muffler is bouncing up and slamming into the top of the tub
