I have two exhaust systems I'd like to sell. The first is a Mac 4-1 for the KZ1000/900/Z1. The Mac website is gone, but I think it's P/N 202-0601..
It's all black paint, not chrome. It's never been used, but it has a bunch of little scratches and scuffs. "Shelf wear" as they say. Includes the hardware bag with brackets and stuff.
The second is an unknown brand, but it's pretty much exactly the same shape as the black one. One obvious difference is that the mounting flanges are captive. Chrome with silver paint over it?
This one does not have a muffler, and has been modified to be a straight pipe. Looks cool, is probably stupid loud.
PM me for more pictures if interested.
