Personally, I don't care for Mike's new Commando mufflers. They're not the same Commandos they used to sell, they're just an EMGO muffler now. They used to be dyno designed and available with a 1.5" inlet so they fit nicely without the need for reducer sleeves. Now they just have some off-the-shelf EMGO baffling and only come with a 1 3/4" inlet, so you need to use those reducers (which always leak, lol). Honestly, I think they're junk now. Mike's headpipes are still nice, so I'd say get those alone and keep searching for a suitable 1.5" inlet muffler.
