@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.
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.
- 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.
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.
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.
I never said it didn't have an expansion chamber. In fact, originally it didn't come with one (this was back before they were on all the two-strokes) and when we put this pipe on it changed it totally. This pipe comes out of the port, does a 180, then the expansion chamber and stinger shoot straight as an arrow to the back. We have a silencer for it, but it restricts the exhaust flow a lot, looks hardcore stupid, cracks the pipe, and destroys the most beautiful engine noise ever known to man.
@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.
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
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.
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
Thanks for the vid, over here in Europe it's getting tougher and tougher with noise restriction laws and actual mobile measurements at often-ridden roads - need to repackage some of mine to keep it on the road!
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.
@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!
@MrTinman818 - Cores are pretty specific to the exhaust. We don't sell cores. I am betting yours are fine, I haven't seen too many go bad. The stock exhausts on that bike may may be "chamber" style and not take packing the same way you see in the video. You will be able to tell when it is apart. good luck.
@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.
@Zeekon - Lexx MXe Premium Silencer Packing. yes it will work on you 2 stroke as well as a 4-stroke exhaust. It comes with more than enough material to do your shorty 2 or 3 times. Cost is $14.99.
check your carb mixture screw and float height, sounds like it's very rich in the low end and needs a good tuning. Also make sure your air filter is clean.
@yamaha250Frider62 - If you stripped the head of the bolt, you will need to come up with another way to get the bolt out. you may need to drill it and use an easy-out.
Well, it's an older bike from the days when silencing wasn't that big of a deal, so that might be reducing that effect a bit. The silencer isn't even half the size of the one in this video. And I KNOW it's faster, because before we removed the packing, it had a very bad throttle response. It was fine up to about 1/3 throttle, but after that it would start to burble and you could feel the acceleration being slowed down as more throttle was added. Now, though, it's got crazy top-end.
No it's not going to hurt anything. That is basically used to quiet the machine down and make the muffler spark arrested. You want to run that in the forest or desert but then it's fine to remove the spark arrestor when riding the track
@JETZcorp - I'll bet it sounds faster with packing out, but I doubt it is. The missing packing will cause a lot of turbulence in the silencer, which interferes with flow.
@MrBrucerx7 - who sells your brand of mini bike? That is who I would check with. If it is some off-brand Chinese bike, you will most likely have a hard time finding one.
On my bike, we just blasted the core with a torch, took the packing out and replaced it with nothing. Power is way up, and it sounds better when you give it the berries. Certainly not as friendly for riding around the neighborhood and that sort of goofy stuff, but we always ride way out in the middle of nowhere so the noise really isn't a problem. My other (smaller) bike just runs a straight stinger with no silencer at all. Totally illegal to ride it after June or so, but she sounds evil!
@RockyMountainATVMC No, unforunately it's a stock one from an old machine and it's welded the other end, i have sort of fashioned a tool from a long flat blade screwdriver but it only reaches halfway, preserverance is the key i guess lol.
@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.
@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.
no difference on power. you want to acheive good sound absorbsion and good heat resistance. Multi layer packing does a good job with heat. The Lexx premium packing is the best we have tested for sound and heat.
not to expensive i just recently bought some at my local motorcycle store and i think it was about $20 but it was alot cheaper than i expected. and i bought the fmf 2 stroke you shouldnt repack it to often like you would with your oil i think its like a couple years after it comes out of the factor that you have to repack it it also depends on how well you mix ur gas if you have a 2 stroke and how often you ride for me i believe that mine lasted from 2006 till today the day i changed it
You never know what you are truly packing, I mean you never know what you buy on eBay.lol jk I bought some silent packing material from eBay it handles 2-stroke and 4-stroke, ATV I think it's a more universal. Anyways my question is, I have a lawn mower, lawn tractor. The muffler is not even a foot away from the head of the engine. It's just a little muffler, do you think it's going to burn up? If so I always got more.
@johndevinaspre676 - steel wool will resist heat better, but isn't as good for sound. i don't know the specifics on what type or size of steel wool to use.
ok thanks because I open my 2 brothers and I found some of stanless steel wool plus the ceramic fiber pad but I order the kit to repack mine and it only come with the ceramic pad not stanless steel wool at all
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?
might be dumd but after im done riding,so kind of smoke comes out of my pipe,i have a 2stroke is it the packing that is burning?that is after the motor is dead
Hey man i have a big problem, only one end of my can is removable and the previous owner packed it that tight when he repacked it that the packing is jammed in and stuck to the sides and i can only get small clumps out, whats the best whay to get the rest out?, i tried a long bend screwdriver to scrape it out but im not having much success, any ideas?, oh yh forgot to mention, the packing material is soaked in oil so it cant easily be pulled out by hand.
I changed out my old packing from my yoshi pipe and the core had steel wool wrapped around it then the packing. when i replaced it i never put the steel wool i just packed it. was that a bad idea? seems to be fine to me.
I have an older FMF universal powercore 4. I got the allen screws out, but I don't know where to tap on the muffler to get the core out. Do I need to drill the rivets out on the rear of the muffler too?
i just bought some lexx repacking material from you guys for my pipe and its not this one its the cheaper kind but iv heard people say to wrap steel whool around the core before wrapping the packing or the packing will blow out quickly is this true? if you could reply it would be appreciated
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 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?
+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.
I have a 400ex. and I run a fmf titanium 4. it has a quiet core insert would it matter if I ran the exhaust without the quiet core insert? will it hurt anything? Please let me know.
Hey there, I have a question. Other than to muffle the awesome revs of the vehicle and to keep things legal, what are the performance benefits of packing a silencer? Would fuel efficiency be improved? Would the bike run less hot? Sincerely hope to get a reply
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.
@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.

Yes it is. It is on the outside of the packing and won't be affected.
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.
@Huff834 - you shouldn't have to pull rivets on the lexx, but if you have a pipe that needs them, just get ones that fit snug in the holes.
@Osballs - yes it kind of looks like string. rocky mountain ATV/mc has a few camera options. I have been using he gopro HD and really like it.
I never said it didn't have an expansion chamber. In fact, originally it didn't come with one (this was back before they were on all the two-strokes) and when we put this pipe on it changed it totally. This pipe comes out of the port, does a 180, then the expansion chamber and stinger shoot straight as an arrow to the back. We have a silencer for it, but it restricts the exhaust flow a lot, looks hardcore stupid, cracks the pipe, and destroys the most beautiful engine noise ever known to man.

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

@yamaha250Frider62 - If you stripped the head of the bolt, you will need to come up with another way to get the bolt out. you may need to drill it and use an easy-out.
Repacking my RS2 was such a pain in the ass and im not sure i even did it right. I recommend just sending it back and not trying to save a few bucks.
@50300 - i put silicone in the hole before putting the rivet in.
it depends on how hard it is ridden, but any 4-stroke exhaust (LEXX, HMF, FMF, PC, etc.) should be repacked every 25-30 hours of use.
@ghat13 - i would try a little heat from a propane torch very carefully. That should loosen it up.
@MrMotorider15 - On the seams? That should already be done by FMF. At the points they connect? A little high temp silicone never hurts.
Well, it's an older bike from the days when silencing wasn't that big of a deal, so that might be reducing that effect a bit. The silencer isn't even half the size of the one in this video.

Like the video says at 1:05, you will have to drill the rivets and re-rivet to assemble.
Good call! i have heard that works great, but have never actually tried it.
@brettwill87 - Yes it does have packing, and yes you can and should change it regularly.
@RockyMountainATVMC No, unforunately it's a stock one from an old machine and it's welded the other end, i have sort of fashioned a tool from a long flat blade screwdriver but it only reaches halfway, preserverance is the key i guess lol.
@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.
you can put a bit of soap or oil inside of the outside tube to prevent hte packjing to shrivel backwards as it slides
Awesome.. Thanks for the inside tip!
@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.
no difference on power. you want to acheive good sound absorbsion and good heat resistance. Multi layer packing does a good job with heat. The Lexx premium packing is the best we have tested for sound and heat.
I use paint roller covers instead of packing. They are so much easier and you can get them anywhere.

question: Is a silicon with max. 300 degrees ok? Thanks!
Nunuatak Nonatakaa 300 degrees fahrenheit? If so i would say get something that resists up to 500' degrees fahrenheit..
thanks! :)
@happywombatproducts - No. I would use the premium packing we use in this video.
@johndevinaspre676 - steel wool will make it last longer, but not as quiet.
I was going to buy some carbon fiber or kevlar cloth on ebay and un-weave it and bundle it up..I heard it makes the sound a little deeper.
my rm 250 sounds very loud as if it did not have the silencer what do you think it's ??
@johndevinaspre676 - steel wool will resist heat better, but isn't as good for sound. i don't know the specifics on what type or size of steel wool to use.

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?
for 2 stroke dirt bikes, if its leaking a little oil out the back of the silencer is that a sign that it needs replaced too?
might be dumd but after im done riding,so kind of smoke comes out of my pipe,i have a 2stroke is it the packing that is burning?that is after the motor is dead
it makes it quieter.
Hey man i have a big problem, only one end of my can is removable and the previous owner packed it that tight when he repacked it that the packing is jammed in and stuck to the sides and i can only get small clumps out, whats the best whay to get the rest out?, i tried a long bend screwdriver to scrape it out but im not having much success, any ideas?, oh yh forgot to mention, the packing material is soaked in oil so it cant easily be pulled out by hand.
how much does it cost to buy the packing material, and the hi-temp silicone? How often should you pack your exhaust?
Thanks!
@Osballs - if you land on it - most likely not.
Badass intro.
@robertgisthebest - I think you have the right idea with the long screwdriver. Or, can you drill the rivets and put new ones in?
I changed out my old packing from my yoshi pipe and the core had steel wool wrapped around it then the packing. when i replaced it i never put the steel wool i just packed it. was that a bad idea? seems to be fine to me.
Run it with just steel whool actually is how they were originally designed.
How is the lexx exhaust compared to stock will i lose any power or gain is IT louder than stock ktm 500 exc 2015
What about a damaged core that’s ripped that pro circuit doesn’t have
I have an older FMF universal powercore 4. I got the allen screws out, but I don't know where to tap on the muffler to get the core out. Do I need to drill the rivets out on the rear of the muffler too?
+iryde woods Yes. Those rivets would need to be drilled out to separate the two.
awesome video !
+Ichiban Moto Thanks. Hope it helped!
Badass!
5/5 stickers!
i just bought some lexx repacking material from you guys for my pipe and its not this one its the cheaper kind but iv heard people say to wrap steel whool around the core before wrapping the packing or the packing will blow out quickly is this true? if you could reply it would be appreciated
Is it easy to remove a silencer? anything bad about it besides louder noise? Thanks ! (on a car)
@RockyMountainATVMC a silencer for my mini bike 2-stroke i need a website or if you no how to make one please tell me.
how many DB less can you achieve when re-packing a silencer?
i have a kx85 and it needs a good repacking job.. Should i use regualr packing or could i use the fmf packing as well?
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

Where can I find one for my 2-stroke pocket bike?? Please reply
@RockyMountainATVMC do you have to put a silencer on an aftermarket exhaust?
@emoskater1212 - when sounds a little loud. Or every 30 hours of use or so.
@ploppinpigeon - a new exhaust will be together and ready to go!
Dude I got this exhaust yesterday
I have a 400ex. and I run a fmf titanium 4. it has a quiet core insert would it matter if I ran the exhaust without the quiet core insert? will it hurt anything? Please let me know.
Will this packing work for any 4 stroke exhaust??? I have a dg exhaust in my 400ex will it work for it??? Please let me know :) thanx!

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.
@Peterrides - either will work fine.
What size Allen key did you use to get the clamp on the side of the exhaust off the Lexx.
does this silence the bike because my 50 cc bike is very loud plz reply thanks
Thanks for the video! Just repacked my pro circuit shorty for my rm125
i have a pocket bike and its very loud would takeing the exhaust tip off and putting steel wool in it help ?
+9992Awesome i wouldn't recommend steel wool. It's flammable. Use an exhaust packing. But yes, packing your exhaust silencer will reduce sound.
@Christian8507 - just the oil in the pipe still smoking.
Anybody got any tips on disaasembling a fmf shorty that seems to be rusted together?
i have the lexx exhaust for my 400ex but i cant find a place to buy "lexx" brand exhaust packing.do you know where?
but most stock ktm from 2003 are clips..so how? no screws just clips
Big thank you for this vid, Very well explained, very useful. You've made my day !!
I wonder what would happen if u put three more layers of exhuast packing would it be super quiet
Crowman Caveman it would be louder actually
@@shredder_mang3211 dam thats bummer i want to be stealthier like electric dirt bikes
My silencer is leaking a lot on my yz85 I NEVER run my bike to rich is it time to repack my silencer? Please respond
do u have to use silocone??
can you use none flammable whool?
@MrBrucerx7 - where can you find what?
can you use rtv to seal it?
Yes.
Rtv stands for room temperature volcanism** so yes.. Means cures from condensation
what silicone do you need.
