Squeaks and Rattles Help Need on a 2007 GT

I replaced the exhaust with a Bassani X Pipe and Race Axle Backs for the 2007. When down shifting or on low rpms the actual hanger begins to vibrate silly causing a rattle in the hanger. The sound is quite annoying, the exhaust is on snug but its happening randomly and is driving me crazy. Anyone have an ysuggestions?

It probably doesn't happen, ever, when you first start driving?

If it onlyhappens after the car warms up, the exhaust is getting longer and one of the bent rods, that hold the muffler in the car's rubber-mounted hanger is rubbing. That's what happened to me, anyway.

Super easy to fix.

Take a big pair of channel locks and bend the hanger away from the place that rubs, or loosen the pipes and shove them in a little farther. Whichever makes you happier.

+1 on JB's comments. You'll need to isolate when hot. Exhaust components can move an inch or more when hot.

Thanks for the thread. I noticed some serious vibration noise today after installing SLP LMs a couple days ago. When I installed, I purposely extended the exhaust tips about 1 1/2 inches out from the bumper cutouts so that the SLP logo would be clearly visible. Plus, I think it just looks kewl. After reading this post, I pushed them back to make sure there was plenty of clearance between the hanger rods and any body part to allow for heat expansion based on JB's post. Will advise if this worked.
