I realize this is an older thread, however, here is my experience with Bub exhaust systems. Love the exhaust note! BUT! After three years of use, the left exhaust has a rusted through (or did it crack?) hole about 1 1/2" wide where it connects to the header. ALso, the pipe within the the exhaust system is diconnected. It's been over a month since I've ridden the bike due to back order issues. A rep with Bub claims that he's having trouble with the chromers.
As a business owner, I fully understand backorder issues.
However, having an exhaust rust through in three years doesn't set well with me. Now they are having problems with the chromers. Do I really want them to send a replacement?
