Is there any maintenance that is needed for this item. I just removed mine and the baffle inside is lose and causing a rattle. Anyone else have the same problem? | ||

I believe they ned to be re-packed every so often... DO you know which muffler it is? Is it he old SuperTrapp style? Or the newer one(no supertrapp)? Chase | ||

If it's an X1 race system like mine (ie NOT the Supertrapp style), yes, a little periodic "maintenance" is required... Pretty much every second oil change I pull it off and repack it with rockwool-style muffler packing from the local bike shop. This involves drilling the rivets out for one of the end caps, removing the end and pulling the core out and what's left of the muffler packing - usually not much! The core is held in place by the end caps. I don't remember the core ever being loose inside mine and rattling, though I guess its possible over time. Maybe a rivet has broken off and is rattling inside? I use aluminium rivets, they do tend to come out over time (one time there were more missing than still left holding it together) but they don't enlarge the holes like steel rivets do. I just treat replacing rivets as a "maintenance" item  The race mufflers aren't round, they're a sort of egg shape - it's much easier to put back together if you make a mark on the body and the caps to show which way they line up when putting it back together  . Hope that helps. cheers, chili | ||

Ditto above. Yep, when they rattle it's time to repack. Typically when you repack they last longer than OEM. Word of caution - factory rivets are stainless which are hard. You need to use a special drill bit like cobalt to get them out. I use aluminum rivets and they work great. Do a search on kv for FULL discusion and procedure. | ||

Saweet, thanks guys!! I think this might be the noise that I have been searching for the past few weeks! | ||

Hey, me too (strange rattling sound)! That's great to hear actually. I thought my muffler might have been more permanently damaged. In your guy's experience, how much would a shop charge to drill out the rivets and repack? | ||
| Cuelbuell |
Just do it yourself. Cost $25 from american sportbike. Just got done taking the muffler apart, and let me tell ya...WOW. Theres NOTHING left! I had about five chunks of fiberglass left in there and that was it, lol. I'm calling american sportbike here in a few to get some new packing on the way. I hate not being able to ride.. | ||

You could always run with it empty . If you like it that way then save for a Force pipe... | ||

If you run with it empty, it'll be more likely that the core will be damaged from the un-damped exhaust and sound waves - it'll fracture over time. The race kit exhaust system (header included) has a reputation for shaking itself apart... it's a good idea to keep the muffler packed. | ||
| Phelan |
Yeah I was just joshin'. The thing's so friggen heavy too. My cap and packing blew out of my D&D slipon on my S2 a while back. I replaced it with a Force pipe last week. | ||

The way to go, IMHO, is to use 4-stroke packing material from your local dirt bike shop. Works better than factory. Get the cobalt drill bit and get to work -- if you have a drill press then that's great. If not, a hand drill works too. I remove the exit of the exhaust myself. Go to your local hardware store and buy aluminum rivets of the appropriate size. If you want to be clever you can tack weld nuts on the inside of the muffler and use screws. I wouldn't recommend self-tapping screws though. Now that you've done your shopping locally you get to chat with your old high school buddies at the hardware store. While there, you run into your high school sweetheart and you find out she's divorced now and is looking for someone to talk to. You find a nice cafe and let her vent while you patiently listen and pretend to care. When there's that awkward silence, you nervously ask if she's interested in going to dinner with you and catch a late night horror movie. You bring flowers (ROSES!) and she's awestruck that you're such a thoughtful man. You let her know what a smart and classy gal the girl is and you make up stories on how your friends really liked her. Tell a few funny jokes and tell her an embarassing story about yourself which humbles yourself but she's falling for you like an English Bulldog stuck in mud. During the movie she can't keep her hands off of you 'cause she's frightened to death. After the movie you have a nightcap at your local pub and escort her home and let her know that you had a great time and you'd love to be able to get together again. A quick peck on the cheek is all you offer her... until next time. And all because you stayed local and you finally realized that your local and really hot UPS girl really isn't interested in you no matter how many times you answer the door in your boxer briefs. | ||

The 'Trapp is good to go. I repacked mine once after about 15,000 miles only to find the packing was still perfectly intact. Generally any exhaust system packed with a fiber media will need eventual repacking or may self-destruct. | ||

Sloppy - I must be going to the wrong hardware store! I use the dirt bike packing too, either the sheets or the loose wool stuff. It doesn't stay in there forever, but I guess I get about 6,000 miles out of it. | ||

Try using the repack kit from American Sport Bike. I did my V&H with it and it's still good to go (as far as I can tell) after 15,000 miles. I don't know what the packing material is, but it's a lot easier and safer to work with than fiberglass. Just don't let the bag it comes in get ripped... it'll blow up to the size of a 33 gallon trashbag. Try stuffing that in your pipe. | ||

I have the race kit on my M2 and noticed that when I tilted the muff from side to side (uninstalled) there was a slight "clunk". No rattles or funny noises while running it though. Should I be concerned? | ||
| Cuelbuell |
Thats what mine was doing. I bought the new packing from american sportbike and am going to install it today. Once thats done its time to RIDE!!! Bikes been down for over a week and its killin me! | ||
| Djkaplan |
"Should I be concerned?" You should consider the repack kit. | ||
| Cuelbuell |
Well just got back from a decent ride, about an hours worth of cruising and a lil racing. I can't tell if the packing made it any quicker as i've read from some badweber's. I do think that the noise I was after is now GONE! But I have developed another noise....the freaking front brake rotor I think is way to lose. On a side note I liked the sound without the packing, lol. It's to quite for me. The louder the better!   | ||

Thanks, DJ. I cant believe that it needs a repack already.(im stating bewilderment, not that I distrust your advice) The thing is practically brand new. Probably less than a thousand miles on it. This may be the motivation I need to get the D&D race muffler. (I like it loud as well) (Message edited by torquemonster on August 25, 2008) | ||

The original factory repack might last 5000 miles. If you do a very tight, quality wrap, it will last for years like what DJ says. Oh, DO NOT START THE BIKE BACK UP IN THE GARAGE OR YOU WILL GET FIBERGLASS SNOW! Start the bike back up outside. Take a few seconds to blow out any loose material. | ||
| Djkaplan |
"...YOU WILL GET FIBERGLASS SNOW!" I've repacked mufflers with that horrible fiberglass stuff. I was pleased to find that the repack kit from American Sport Bike uses some kind of filament that's not irritating at all. It's a little harder to work with (it's like a huge ball of wool in a tubular bag) but it won't blow out through the perforations in the core like fiberglass will over time. | ||

Actually, it was the American Sport Bike repack kit that taught me to not startup the bike in the garage after a repack... I haven't seen much of a difference between other brands of repack (but don't use the loose 2-stroke fill). My favorite now is FMF or MOOSE 4-Stroke repack mat -- it's a carpet that you roll tight over your tube and trim to size. | ||
