I’ll try to glue it after deciding on the best stuff. Maybe epoxy, maybe something else that will both flex and resist heat.

There are plastic aftermarket numbers but they are noisier - the fuzzy dampens the noise. If mine tore I would consider glue and high-temp to be a better option.

If mine tears again I’ll probably just lighten my wallet with the brand-new correct OEM part.
I use clear silicon to glue mine back together….flexible, unlike epoxy and heat wont hurt it….

Never use silicone where it is possible to get into the catalytic converter. Metallic duct tape works great for repair. Dryer hose from the hardware store works well.

I made sure it dried for about week and half before I cranked it…..and that there was no frazzles of silicon that could break loose. Been working fine for 35,000 miles.

No I have seen what happens to a catalytic converter damaged by silicone, and Dexcool and engine oil! It’s nasty! Pulls right up!

Silicone and heavy metal molecules are deadly to the catalysts in the converter. It is a science thing.
