Default Re: Does anyone know who builds custom exhausts?

That ebay pipe looks all wrong. The header pipe looks way too long for high rpms. If anyone's running that pipe, I'm curious about how well it works.

I'm making expansion chambers that will clamp on to the stock exhaust header. Just cut the muffler can off and clamp it on.

There's a post in the intake/exhaust section with pics.

For the Predator 212 on a bicycle... I have not yet seen a pipe+muffler kit specific to this, just lots of alternatives for karts. Some of them look like they might work, but maybe not. The best alternative I've seen to this point is the "U Build It" collection of tubes like that found on the OMB Warehouse site.

Given that I can get a 1" pipe around the frame, away from chains/belt/legs/gas, can someone suggest a quiet muffler? Anything has to be better than the lawnmower box that comes standard.

You can use a small glass pack muffler designed for a moped. They sound great and are cheap to service. I just repacked mine for $15 and I still have material left for one more pack. These work great on 2-strokes as well.
