I bought an exhaust system off another bike expecting stainless, but got titanium instead. Something to watch out for.
The largest cup I have I think is a 10. The tubing is .065.

The exhaust header is made of Ti. So is the mufflers. But as you know, I just need to make a mid pipe that will connect the two.

I need to order a few exhaust pipe expanders. Once I get home ( at work offshore), I will fit everything up, then start ordering stainless pipe.

Do you know where I cold find some locally? Like maybe a exhaust shop or something?
