Nathan,
My first instinct was to say the same thing. I must admit though, this was a rough search to find out. Went to Slimline and Bisson's sites and couldn't find anything. As a last grasp I checked the manuals for the dimensions of the exhaust ports, but neither manual listed the size of the port. And then as I was ready to give up I came across this in each manual. The part numbers for the stock mufflers. They are identical. SO..... Yes, the same pitts muffler will fit!!!!
