Re: Have any of you ever taken your bike across country?
It's a homemade concoction of 3/4" copper tubing, fittings, and a 3/4" old riding mower muffler with a bit of steel wool to 'mellow' the tone --- brazed then wrapped with an epoxy tape-like substance. It works very well. I've had the OE type muffler, an SBP expansion chamber, and my frankenstein on the bike. I like the frankenstein the best. Maybe not as much power as with the expansion chamber, but it sounds much better.
You're never lost until you run outa gas.
