Rotax 582 muffler bracket

Hello.

I am going to install a new exhaust on my Avid Flyer as the one I have is heavy and has modifications 
made by the previous owner. Do you have any dimensions or drawings of the muffler support? I've seen photos 
on the forum and they are two pieces.

Thanks, as always

Those mounts are subject to cracking.  You are better off hanging the muffler off the firewall.  I welded plates on the ends of my muffler, fastened pieces of aluminum angel to the firewall and used some rubber belting between them.  It worked fine, and allowed me to make a wider muffler shroud for cabin heat.   JImChuk

I appreciate your solution, I had thought about this solution, but I was worried that it would
 have cracks due to the vibrations of the engine that is hanging from the rubbers. The bracket
 I have now has broken the bolts on the exhaust motor outlet. If you have this solution
 validated, I would appreciate photographs and details of the attachments to the firewall. With
 the one you sent I don't see it well Thank you.

Finally I carried out this solution, but with an improvement, I used metallic antivibrator, since the rubber ones could 
be affected by the heat of the exhaust, I provide the solution. Thank you all.

Rubber has been used for many yrs for muffler mounts without real problems I think, but there is more than one way to skin a cat.  Universal Exhaust Hanger
