When I was running the stock engine, I modified the stock muffler to make it less restrictive. Others have use motorcycle mufflers, atv mufflers, tractor mufflers. Your 4 stroke engine is easier to match something up than it is for a 2 stroke.

well wound up finding a 250 4 stroke japanese muffler.cut off old muffler notched new pipe(found muffler at Bobs Used Motorcycle Parts in downtown Phenix,then put old muffler exhaust pipe on and clamped.gonna make a stud from the frame to the new muffler and put in a bolt hole and attach. hope the pictures come out.entire job,me and my friend took about 3 hours. real happy with results

umm I hope this is a mock up photo.
you have the muffler attached to the frame with no flex joint. as soon as you hit a bump it is going to bend the pipe. Even if you attach to the rear suspension frame that the motor is attached to. You will need to put some flex in the pipe as the motor will move relative to the rear axle.

Nice!! You do want to mount it to the swing arm so it can move with the engine.
