some pictures of standard FORA muffler fitting

I borrowed this fitting from Alexey Tapunov (Chicago IL) and find it to be one of the best fitting solutions for that type of muffler. Very easy to install and quick muffler change/replace if you need to.

Also there is a small trick in there - the rubber seal was thrown out and made a Teflon one - it made the exhaust pipe and the muffler connection just perfect. And due to Teflon's temperature resistance property that kind of connection lasts just forever.

but native crappy rubber one can also be used  Grin

Here is how I fixed a standard FORA muffler when I used to use them.
A piece of 0.6mm multi stranded wire and some soldering job

Here some tips to make a muffler hook by yourself.
I figured the best material would be a bicycle spoke 2mm in diameter. This material is very easy to deal with: bend, cut, file and etc and the final product is quite strong and has acceptable weight parameters. Weightwise the best material perhaps would be a music wire 1.7mm in diam.

I made a few close-up photos from different angles. The hook is combined one (muffler + streamer), I borrowed the idea from Ukrainian pilots.

Hey guys!

Just to let you know I finally arranged the production of industrial grade streamer hooks, muffler holders etc.
All the stuff is made of carbon steed and nickel plating finish, so they look really cool and you can snap on and off easily.
Here is the first one I have in stock and more coming
