Try it and see. If the engine doesn' t overheat, you'll be OK. Many muffler makers use the same size can and pipes and just change the adaptor to fit different engines. The main consideration is making sure your engine gets good air cooling inside the cowl. Make sure that air coming into the cowl actually passes through the engine's fins.
