Do you have a YZF or CRF motor? The last couple hybrids I have done I used a YFZ450 slip-on exhaust. Not a slip-on that has a mid pipe, but just a slip-on that will work with the stock headpipe. I then used the stock CRF or YZF headpipe. I found the YFZ slip-on to have the closest bends to what fits. I did modify them some though. If you need to bend the silencer to meet up with the headpipe better, just make a cut with a cut off wheel, on a die grinder, 3/4 of the way through. Then cut a little wedge out from the side of the pipe you want it to bend towards. Bend it to how you want it, Mig or Tig it back up and there you go.
