Good call! i have heard that works great, but have never actually tried it.

@happywombatproducts - yes it makes a difference. Steel wook is used on some bikes right around the core, then packing around it. The steel wool is better for real high heat - it won't burn out as fast.

Yeah it's probably time for a repack. Also when rebuilding the silencer i would stick a little silicone on both the front cap and your rear cap to seal it up a little better. If it still blows oil i would look into jetting

Yes it is. It is on the outside of the packing and won't be affected.

@MastaSquidge - I did that in scouts too! Most OE 4-stroke exhaust cores are wrapped in steel wool. I don't know what temp it burns at, but it must be OK for the most part.

Yes this would work for just about any exhaust. The steps in the video may be a little different than what is involved with your muffler but you should be able to get it with referencing this video. There are tons of aftermarket packing out on the market but any packing would work so long as the length is correct or close.

Hey, nice vid! Im using some basic FMF packing now and am due for new one! I was wondering what are the difference between wool(what I have now), carbon packing, multi-layer and the premium packing??! Is there anything performance wise?

@rmatvmc 12 жыл бұрын

@raptorandblaster - I would recomend the Lexx. It is tunable so you can open it up. any time you open up exhaust or intake it will effect jetting; so you may need to go a little richer. Regarding the "loud" keep in mind that you only want to be loud where it won't affend anyone. Noisey bikes and ATV's don't help to keep riding places open. thanks!

- we have lexx packing as low as 5.99. The premium packing shown in this video lasts longer and is quieter - we sell it for 14.99. We sell permatex hi-temp silicone for 5.99. It depends on the bike, bust most exhaust makers say every 25 hours. I do mine every year.

Some mufflers and silencers use rivets to attach the canister to the end pieces instead of bolts and in those cases yes a hand rivet gun would be applicable

Hey there. Thanks for the video! I'm going to repack the two stock mufflers on my 06 Ninja 250 and I'm pretty sure I should replace the cores as well. The previous owner let the bike sit and rot for a few years. Do you sell them as a kit (with the packing materials and the core)? And if so, are there different sizes to fit different bikes? Thanks.

you most likely have some jetting issues, but packing the silencer and cleaning the pipe can help. It will certainly help the noise.

@rmatvmc 12 жыл бұрын

@1PSYTEX1 - yes, to some degree. it is mostly there to protect the rest of the exhaust from heat. It doesn't burn up as fast as other packing material can.

@Osballs - I guess it depends on what is hanging out. It is worth pulling apart to see. it depends on how bent it is. if it disrupts flow it will have an effect on power.

When packing burns out it leaves voids in the canister. This does a couple things. 1. it causes more heat from the exhaust to transfer to the canister. Heat can ruin the canister. 2. The void also causes more turbulence with the exhaust flow, which negatively effects the power.

How often should you rpack an exhaust cuz I got an r4 and I might need to do it soon I've had it a while and also if I have a slip on exhaust do I need to rejet I'm going from stock to another white bros r4 and when I put it on my quad staryed to smoke really bad I'm not sure if its because its been sitting all winter or if its the motor messedx up cuz I didn't jet it or if its cuz the exhaust sat in a barn for 2 or 3 years before it was put on

I'm sure modern bikes are designed to be fitted with mufflers with lots of packing and would be negatively affected by running a straight stinger. But my smaller bike was made in 1967, when no one even thought of putting mufflers on a bike. It's made to run open, and it does. We have a silencer that we occasionally put on it, and it destroys the power. Takes the most radical and torquey 115cc bike I've ever seen and makes it into a turkey. We found the same on my dad's '73 Yamaha 100MX.

I'm not really sure what you are asking. Are you trying to figure out which packing to buy? If so you just need to measure your canister and the packing should say what size it is so you can compare it to that but most all aftermarket packing will work with just about any canister.

@rmatvmc 11 жыл бұрын

If you are looking for a good sounding deep exhaust sound yes this packing is necessary. Running a muffler with old packing or no packing will rob power from the motor and isn't going to allow the muffler to work as it was designed. Repacking a silencer or muffler will restore lost power and restore the good sound as well. We want to be able to continue to enjoy our sport without offending others so monster noise are not what mufflers are designed for.

I bought an old 2t KTM 250 EXC off a mate and I think it will be too loud to pass rego which I need so I can go to National Parks and such. It's got some sort of fmf pipe on it, is there a specific type or brand of packing material that will reduce the noise to a minimum or is the pipe that's on it just not designed with noise regulations in mind?

@rmatvmc 8 жыл бұрын

+MaggotDiggo1 Your silencer should be stamped somewhere stating 'U.S. forest approved'. There are different brands available but we like the Lexx Premium Silencer Packing. I don't think there's some brands that quiet better, but i have had experience with some lasting longer. But again, it all depends on how you're jetted? More rich or more lean.. that will determine how often you will need to repack your silencer.

@RockyMountainATVMC Steel wool is flammable, just a heads up. Take a 9 volt battery and rub it on the steel wool and you will have a fire in your hands. Used to do it in boyscout meetings... Anyways, a friend of mine made his own exhaust for a 50cc scooter and after only a few miles it started launching clumps of flaming steel wool. And yes, it wasnt a well designed muffler, but fiberglass lasted much longer. Just a thought, im sure there are some types (grades?) that wont catch fire.
