Broken Exhaust Hangers

I've gone through at least 4-5 sets of exhaust hangers. You would think with an exhaust that is half the weight of the OEM one, they would be able to handle it, but I guess not.

Has anyone found a solution for this? Sick of breaking them, seeing my exhaust hang and having to replace them over and over again.

I have not had this problem, but maybe your exhaust is the problem. Perhaps bad fitment stretching it out? I have only recently installed my aftermarket exhaust so I have not experienced anything yet.

Possibly, but I don't think so. I've had this issue with stock section 1 and 2's, aftermarkets, and now with the HPF downpipe/section 1. Also have had 2 different aftermarket exhausts.

Metal reinforcement ones? I'm in the market for 2 new mounts and have only seen the rubber ones (P/N from realoem).

have you tried silicone seal? i recently went through the same trouble. instead of getting new ones, i used silicone seal to fill the empty spaces. 200 miles so far, not seeing any problem yet.

p.s. also running ss race here

That is one method I was thinking of. but wanted to hear others opinion and things they have tried. I thought this was a common issue, but I guess not...

When you guys say filling with silicone, do you mean filling the entire empty gaps?



One of mine broken, horizontally across the inside rubber piece. Should I just silicone that part back together, or lay it down flat and silicone the entire inside?

see that's the rubber one I'm talking about
OP which are you using?

or

2.


you must also get the metal thing off the old one and onto the new one
so it'll look like this

Wow didn't realize you guys were talking about the rubber mount part! that's insane. I just broke my hanger off my exhaust at the weld, but that was an easy fix.. I should have checked my mounts too. And the silicone idea is great! I'll have to pick some up and fill mine.

I reinforced my rear muffler hangers by filling ALL the void areas within the mount with 3M Window weld urethane. Cures in a few days but once set it is as sturdy and strong as the dense rubber.
