    Default In my never ending battles with tinkering...

    ...I pulled off the end cap of the right muffler to see is there is an easy way to give the bike a little bit more rumble. Under the end cap reveals a fully welded and sealed end of the muffler. No easy way to get that off to modify a baffle or two. I take a look down the muff from the back end and see a baffle (for lack of a better term) inside a ways. On the outlet side of this baffle are holes in the main exhaust leading to the outlet. So, the exhaust gasses must come through the cat at the front of the muffler and empty into some type of chamber and pushed around the baffle and into the holes for the outlet.

    The baffle is 12" inside of the outlet pipe and what I don't know is what is on the other side of that. The guys at the shop believe if it like many other Yamaha Star bikes, it is an open-ish type area. My question to them was this...if I was to drill a 1" hole through that baffle would I damage anything on the other side? They weren't sure but didn't think so. The lead mechanic was going to try and find out how the muffler is constructed and that will tell me if I am safe to drill of not.

    I'm reluctant to do it without knowing what is on the other side because if I damage something there are no aftermarket mufflers out yet, or heck, not even any OEM mufflers available to replace it with so I am going to hold off for right now. I'll be down at the shop tomorrow and hopefully he will have an answer for me.

    Is it easy to get the muffler off, to have look from the other end?
    How are the mufflers supported at the back ( bracket )?
    Maybe you can do like we've done on the RSVs, Harley mufflers or Monster Ovals etc.

    That looks to me like the old Harley muffler design. That said from the inlet side take a 1/2 rod and punch the freeze plug out and let her breath easy with a better exhaust note.
