I’ve looked at tractor,atv,motorcycle and old Toyota mufflers for the little blue bomber. I came a cross this company Ipunkz Exhaust System. I was wondering if anyone has every used them or heard of them? I have seen them on a couple for daihatsu, kei and mini trucks sites on Facebook. Here’s what they have for the Hijet S83P. Maybe someone has a link to another place or ideas for a exhaust system. Keep on mini’en

    I’ve been thinking about installing a 1-1/4-inch exhaust front he mainifold back, with a SuperTrapp, muffler at the back. That way I can tune it as needed, and have low restriction.

    The pricing on those pages if way more than I want to spend. they appear to me to be a lot of dollars for bling to impress the unknowledgeable. The engineers at the factory spend quite a bit of time developing a balanced exhaust system.

    You would need to do a lot of internal modification to the entire engine before you can gain any more power or torque, from installing headers. In fact most mods people make to their exhaust systems, actually hurt their performance, unless they have done extensive changes to increase, compression, and increase air flow through the engine.

    Most “performance” exhaust systems actually decrease the low end power and torque, because they are grossly oversized, and far exceed the capability of the valve train to move air through the engine. Thus they completely destroy the ram effect you get from a tuned exhaust.

    Back pressure = torque. Last thing you want with these vehicles is less torque.

    YES, that is why I would install the SuperTrapp muffler. By adding and subtracting plates you can increase and decrease the back pressure to tune the torque curve.

    Bought this motorcycle muffler off of Amazon,just cut off the old muffler and slipped this on and welded it. Not pretty but functional.
