Excellent. I'm starting to get folks wanting me to build exhausts. I'm trying to avoid it - way too much work for the amount I'd be able to charge. But - at some point I may end up getting talked into it anyway.
Typically about two weeks or less. Depends on if I have the metal in stock....usually I do.
I've learned the same thing about full systems. I don't lose money on them, but you end up working for a pretty low wage. And with my manual bender I have to have the bike right there for test fitting....about 20 times.
A computerized bender would save me a full day of labor.
