honda 13hp clone exhaust flange on OldMiniBikes?

ive got a honda 13 hp clone off a genny, swapped the crank for a straight shaft to put on my John Deere AMT. didnt come with an exhaust so i need a flange, does OldMiniBikes sell one? i saw a few different things on there but mostly looked like smaller clone stuff. i need to order some from OldMiniBikes anyway so id like to get it there. :shrug:
yeah well im lazy. ive already got to make the freaking brake pads for it (or pay 160 for 4 pads) and rebuild the front end, and build a cage for the cab... custom exhaust... etc etc etc....
