I don’t have any mufflers here but have muffler gaskets I never used when I had a GP. 38mm bolt spacing and a rectangle port 18 x 28mm.

GP 123 muffs are tough to find and not cheap when you do. DA 120 has same bolt pattern but you need to use an adapter from Plane Bender to go from round to square port and that all costs even more. DLE 111 mufflers are super close and much cheaper/available. I'm thinking of 2 ways to make them fit. First is to slot the holes in the muffler and do not use a washer on the muffler bolt. The other is to install a threaded insert into the exhaust flange to drop the size from 5mm down to 4mm.
This is EME60/120 (DLE55/111) gasket with PTE gasket and muffler. It's super close. I'm thinking of going with EME 120 muffs as they seem to have the lowest frontal profile for my very tight laser cowl |
