    Mine stay in just fine. I had them in for about two weeks and now about 135 miles. I've measured a couple of times after rides from the end of the fibrosleeve to the end of the tail pipe and I haven't noticed and movement at all. I took mine out to take pics for the tutorial and then put my original ones back in. So I haven't had any problems.

    Well, it sounds more like a harley now that it did with just debaffle and demickey. An M50 will never have the same "potato, potato. potato" sound as a harley due to engine design. But it sounds much better, like it's got a bigger motor. Prior to the install, when I'd rev up the bike inside of the garage, it would make me cringe just a bit. It's not really because of the loudness, but because it was kind of a noisy loud. There was this kind of hollow, metally noise mixed in with the lower growl, kind of like a lawn mower and a harley parked next to each other with both running. That's what made me cringe a little bit. But the fibrosleeve seems to absorb the high frequencies and the natural resonance of the exhaust pipe and now I pretty much hear just the growl part. It decreases the volume just a smidge. If you have debaffled and demickey'd and want to go back to the volume of the completely stock pipe, then this will not be the answer. It's almost as loud as before but a much better loud.

    And I got your PM. I'll be going by the post office Monday to send them.

    I did the standard debaffle with the double hole saws. There's a great tutorial here: De-baffle this!

    Thanks for the link DJ,

    I have seen that video several times, and am very familiar with it. My question is regarding the leftover burr all around where the end plate used to be. He does not talk about that in his video.

    Your pipes look perfectly smooth and I am wondering exactly how you cleaned up the left over circumferential burr?

    I know of several ways, but am just curious how you did it?

    Thanks again DJ

    Actually, I didn't do a single thing to clean them up. I just drilled them out with a hole saw just like in the video. I used new, good quality hole saws. But seriously, what you see is what the saws did. The saws, when set up just like in the video, fit snug enough to keep it from moving around by just loose enough to allow it to spin. It really is an ingenious technique.

    I did some experimenting on the fibrosleeves today. I pulled them out, did some cruising around town and then put them back in and cruised around town some more. Then got on some open roads and ran her a littler hard. I then took out the fibrosleeves and and ran the open roads again. I'd say the fibrosleeves quiet the debaffled/demickey'd exhaust buy about 25-30% during the points were open pipes are the loudest- WOT, running at steady highway speed and on deceleration from a higher RPM range. The volume at idle sounds about the same. From idle to redline, though, they sound deeper and much better.

    You've got me seriously thinking about it. Basically, what you've done is stuff the insides of an old Cherry Bomb into the stock M muffler. Love it. I think you're probably going to have to repack every year or two, so don't give away all your leftover mesh. I suspect it will start to rust/corrode after a year of temperature extremes in the pipe. But it's so cheap, who cares?

    Oh, and I love how you're sticking with your name -- the fibrosleeve. Gotta catch on sooner or later, right?

    you know, oldie...I have a spare set of stock pipes if you decide you don't want to debaffle your own. Short drive, cheap price.

    That's what I used to wrap my Cobra Streetrod baffles, much deeper sound and not as loud. I recommed doing this to anyone who wants a deeper sound.

    Digi

    Have your stock pipes been debaffled or are they still factory?
    I already have 8ea. 1/2" holes in mine and might as well debaffle those if yours are still factory.

    Either way, PM me with a price.

    I am planning to debaffle, one way or the other, and add the fibro sleeve as soon as I get the inspection done in a week or 2. Heck I may even demickey. One step at a time, however

    Either way, pm me with a price.

    Hey Mr. Jim.

    Looks like I'm going to do the modification. I have a C-50 (that's me on my bike).






    Is your method still a viable option for this bike?

    I bought the stuff to do it and it only cost $61!

    Could you look at the pics I have, and see if I have the right items.... especially the Fiber Mat. I got it all at Home Depot, but not too sure if the mat material is the right kind. If it's not I'll find the right stuff.

    What's demickey? And is it necessary to do before adding the sleeve?

    Any input is greatly appreciated.

    Ernie.

    Cool, Cajun. Looks like you've got all the right stuff. The only thing different than I used is the fiberglass. The fiberglass that you have looks like it will probably work good though. From the pic it looks like a sheet that is folded and then folded again. It's hard to tell how thick it is because it's compressed. I'd recopmmend opening it up, unfolding it and letting it expand overnight.

    It also looks like you're handy with the camera and making good posts with pics. If you can, take pictures as you go along and keep us updated. If you have a way to record sound, record before and after.

    Roll the wire mesh so that the points of the diamond-shapes in the wire pointed in line with the ends of the muffler (front and rear).

    Good luck.

    I've seen a lot of posts on drilling some holes in the end of the pipes for improved sound, and I am really itchin to do it. All the posts I have seen have people drilling holes around around the inner pipe. I have a friend that has an m109 and he drilled holes into a plate that's about 10" into the inside of the inner pipe (he used a really long drill bit) and it sounds great. Not much louder but a deeper, more throaty sound.
    Anyone done that on the m50? I looked inside the pipe and the only plate I could see seemed like more than 10" in. I don't think I have the cajones right now to de-baffle and it's my first bike. I'm just afraid to screw something up and any ideas would be helpful.
    Thanks.

    So I took off the exhaust/header plate.... I'm pretty pleased with the result.

    If I pull the baffles will it sound the same only louder? Or is it going to be a different sound altogether and louder?

    Just wondering.
