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.

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.
