That engine is a 4 stroke and I find exhaust runs hotter on them so the neoprene may not handle the heat. Another item, I find a long piece of tube may effect power output. An inch or two should be ok. Try it and see how it runs. Can you get a muffler with longer stacks? Maybe a Bisson muffler? I see he does not list one but I know the Bisson boys and they could modify your existing, just have to ask. I also know the guys at KMP, ask them for suggestions, again good bunch to deal with.
