    Saw this and like the look of the exhaust pipe and I'm using that same engine.

    Anyone using a long exhaust pipe like that one on the bike linked above.

    My main question is would that be louder then stock and would you gain or lose performance?

    I don't know with these small engines if you would have a problem with back pressure or anything like that? Seems that a long exhaust might be too long for the exhaust to proper flow out?

    Also that is just a straight pipe so I'm thinking it would most likely be louder then stock?

    Anyone using an exhaust on their 4 stroke that is quieter or adds performance? Doesn't seem to be many exhausts out there for a 4 stroke engine or at least that I can find?

    Going to build another bike but I'm upgrading everything form a basic bike to a mid range bike. Thought an exhaust pipe might be cool. Lawn mower looking exhaust on a Hausheng, not so cool.

    Yea stock is junk but a long pipe like that will be quieter than a short one and have more torque.

    Your stock engine has a 'can' exhaust mounted to it.
    This is because the engine is designed to sit in one place in a small package and turn a generator or the like.

    They run better when you free them up with free flowing air around it, and free flowing exhaust.
