Cat parts has the exhaust pipe if you want new

Ah, that might be a bit trickier Firecat - I was thinking of the regular up pipe. In any case, I call Milton Cat in Batavia NY for parts. But if they don't have one (8F4192 pipe if you have orchard fenders, 6F9829 if you don't), then I know a custom exhaust shop can make one, quite cheaply and you get a choice of mild or stainless steel. It only has two bends, a mild steel flange, and a small rear bracket. I could whip one up in 15 minutes if I still worked in the muffler shop. Best if you have the old one for a pattern, but if not, you can take a piece of mild welding rod and bend it as a pattern, they'll bend the pipe, you bolt the flange on to the manifold, then you tack the pipe to the flange
