Hi guys, do y'all know if the stock exhausts on the Duke and RC bikes are the same? I mean, I'm sure the end cover is different on both, but the basic structure and entry/exit/mounting points, are they common?
I just bought an almost new muffler from an RC390 owner and it was identical to my Duke muffler. I got a little carried away when I ground off the mounting tabs for the chrome trim & outlet pipe so I needed another one to grind smooth & ceramic coat.
