2012 S4 Stāsis muffler
 

I need some advice.

I have a 2012 S4 with the Stāsis aftermarket tuning package. I love the thing to death! I noticed that my exhaust was hanging low on one side. My mechanic says that there is a hole in the muffler where the stainless steel bracket tore off a piece of the muffler housing. Apparently it looks like this happened when the car bottomed out at one point. It's clearance is very low. I try to take everything at an angle but apparently there was one time where I didn't.

Stasis is, unfortunately, no longer in business. Any ideas for me on how to best address this problem? Thanks so much for your help.
