Re: Finally! Hello
If you've been researching you've probably seen some of the 'custom exhaust systems' that have been built by others. There have been some very innovative ideas offered up here.
Personally I've had good luck using 3/4" EMT thin wall electrical conduit. It can be bent and welded and formed to shape around pedals, frames and rear wheels. I like to extend the pipe to the rear then weld the kit muffler on at the end. Of course this requires brackets /hangers to support the weight but if you're handy with metal that shouldn't be a problem. As for performance my bikes do just fine. I'm not out for all out speed but my long pipes don't seem to slow me down much, if any.
Some will recommend an expansion chamber but unless muffled, which sort of defeats the purpose, they can be louder than the stock system.
