Longer Exhaust

[Classickswagger]

Does anyone know what the best way to extend the exhaust on these bike are? I`ve seen some posts about using flexible steel tubing, some about welding a pipe on and some say you should put an expansion chamber on, I would like to route the exhaust behind me( so it doesn't get on my clothes) while increasing or keeping the performance equal, any tips? Btw it has been performing well with a top speed so far of 51Mph on a slight downhill

Best bolt on is a mz65 clone and a slip on muffler for a dirt bike. Other than that, its build your own. I need a sheet roller an ill will be making my own expansion chambers. Best dirt bike pipe is a mz65 or an 80cc dirt bike pipe. Heck even jog scooter pipes work well with our engines.

It would be cool to try hydroforming a pipe.

Done it. But i dont have a pressure washer anymore. Its easy to make a mz65 clone with hydroforming. Really easy.
