chipper, You have an HS series exhaust on their, either 4 or 5hp (depends on the flange). I Have H35 headers getting new cans put on them this week. I'd be willing to trade if you wanted to get the exhaust in the correct orientation (more centered in the frame), have the flange fit the port, and be able to put the air cleaner in the upright position so you have more adjustment room. I have more HS engines than I do HS exhausts, and vice versa on the H ones :doah:
