Anybdy know of a smoke muffler for a Brison 2.4? Preferably pitts. Thanks

Have you asked Brison? If they don't have any or can't recommend any Fox sells a Peace Keeper muffler that ready for smoke for about 99.95, I think. www.foxmanufacturing.com
It should mount the same as Brison and Fox us the same piston and cylinder assy.

Slimline also sells a muffler for the Brison.
