Wow the fact that this manufacturer is will to share this information speaks volumes for this company. I’ve got yoshi’ on my Aprilia and it sounds awsome.
Thank you!!!
When a company gives you tips about on what to look for if you need to repack is just like how old youtube does things, no bs and straight to the point. I wouldn't know what to look for even if I tried and would think "Oh dude, look at my titanium esq muffler so cool" 🤣🤣🤣
I’ve dealt with the top blokes at Yoshimura,the customer service,pricing,parts availability and advice is top notch.
Cheers from Australia.
Cheers!
this shows why Yos is the only brand of exhaust i run .. service is top notch
Just installed the Yoshimura R77 full exhaust on my 2020 Yamaha MT-03 and I love it!
Pop's I'm sure would approve & the final end cap high temp sealant shop trick with a very thin layer of material looks like a pastry chef decorating a Wedding cake with high real ingredients icing. I'm a very good Used 2000 RS-3 Carbon fiber body bolt on today from Ontario for $185+ shipping and planning on shipping Yosh pipe to you guys for a Repack and road rash repair end cap on the mid pipe location and watching this I'd prefer the pros to do it & she will come back looking & sounding like new Again with the proper weight of repack material. Thanks for the video it's definitely a rewatch over & over again for me, Plus Kevin Swantz is one of my favorites pro riders ever in the Non robot IMU bike era on the 1980's till he retired.
Great tech tips. The yoshi revits on the website came in clutch. Back in action..braaap!
Being able to send it back to Yosh to have it repacked is a great benefit! Makes me wish I had purchased Yoshimura exhaust for my KTMs
Very good video and thxs for explaining some of the specific points along the way...
Thanks for watching ...and learning!
Great tutorial! Thanks guys.
Any rivet gun will do. And this info is available anywhere. This is an easy job.
I just spoke with Monica on the phone like 30 minutes ago… wonderful customer service!!! Nervous to do this to my trc but I’ll get it all ordered and I’ll get it done. Thanks guys!!!!!
Thanks for the kinds words. We appreciate it!
@@YoshimuraUSA send me address and phone number please I’ll be sending my exhaust to you
Good info. Thanks guys
The best Yoshimura 💪💪
great video guys
Great info guys.
Thank you!
This is a great video. Thanks guys
Glad we could help!
Thank you so much for the video guys! You rock. I have a Shorty Off-Road Model from you guys. It is very loose and wobbly. Would a repack fix that? The metal base of the exhaust tip is very sturdy but the rivets seem very loose and so does the carbon and the rest of the exhaust after the first rivet band.
I have a Yoshimura in my KLR650 and I love it. Wondering if I can add one in a VW Rabbit 1.8 and be good???
Would a cheap manual rivet gun work, if used with yoshi recommended rivets?
Did mine, ❤️it, Like brand new now
What kit will I need for the RS-4S full exhaust for my '13 Ninja 650?
Gud jaab , Mite . Cheers from india.
Interesting thanks
I have a full system yoshi on my 2017 grom since day 1, it has 48k miles, I think it's time to send it for a repacking.
When you are ready, we are!
Can i order directly for my xr200? Living here in the philippines
I have pulled and repacked 3 times and its louder now than when I started. I'm going to ship it to you.
Good call!
is it supposed to be quieter?
@@Kevin.OBrien44 as a general statement, yes!
Yoshimura power
"Massage the end cap off." I've always referred to pounding something off or pounding something loose with a BFH as "persuasion."
Great video, very helpful. Are you able to install closed end rivets using a hand riveter?
Not correctly.
@@YoshimuraUSA Okay thanks for the clarification, are there different kinds of rivet guns or just pneumatic?
@@davidpirro1326 Pneumatic is the best way. Harbor freight is a cheaper option. Home Depot, Lowes al have them.
@@YoshimuraUSA Awesome, thanks so much for the help!
@@YoshimuraUSA And what about those drill bit riveters?
What kind of fiber you used? Do u recommend me use a fiber clothe used for making a fiber glass?

Hey i have a 2019 drz400sm i already have a yoshimura exhaust rs2 on it but its damage...i got an offer on a drz650 yoshimura exhaust..so I'm asking can the slip on work with the pipe from the drz400sm
please call us 800-634-9166
How do I determine how much packing I need to put into my stock YZ250F muffler? It isn't in the manual. Do I weigh the old packing and add roughly 100 grams or what do you guys suggest?
We have specific weights for each bike and muffler. Call our office and we can give the amount needed.
I just purchased a Honda African twin with a RS-4. This exhaust is way too loud for me. What do I need to do to quieten it down to a more reasonable level?
Thx
We make a spark arrestor for it. SA-19-L that will decrease the dB nicely!
Currently have the RS-5 for my 2007 Cbr600rr. I recently looked into your website, and was noticed that you guys have an office in Chino, CA? Will it be possible for them to do the maintenance? Not tryna pay for shipping...LOL
Yes please call us and get an RMA number, that way when you drop off we can get you in and out quicker. 800-634-9166
Great Vid! Trying my Akra can. Can't get the front cap off, looking for tips.
good luck!
I got it off. Job is done. Nice tip about the weights.
What happent when we insert much ceramic wool, plz reply is anybody knows the answer
So what is the price range for repacking? Curious to know,because on my cbr1000rr my yoshimura r77 exhaust does not sound the same anymore, before it had the deep sound, know it's like no depth to it
Give us a call and we can get you a quote. 800-634-9166
If I have a yoshimura exhaust for my 2016 can-am renegade 1000 xxc where would I purchase the repack kit? Also when it comes time to repack it would you guys do it? Thanks
We can repack it! Give us a call!
Yoshimura R&D of America, Inc. ok thanks I don’t have to yet but when I have to I’ll let you guys do it probably.
Do you guys work on cans that have been cut down, just purchased a used bike and I like it loud but it's a bit too loud yet I could not do this job myself, please let me know
We don't work on and we cannot recommend cutting down the canister.
@@YoshimuraUSA ok, thx for your reply
If i want to make the muffler louder can i insert a bit less packing than recommended?
if you run less packing it will heat up the components inside the muffler and compromise them. We would NOT recommend this at all!
I’ll do it myself. Thanks.
What size are those rivets?
What is the quietest packing for my muffler??
The kit that is spec'ed for your bike
Was told to use 2.1lbs of packing for my 2022 yz250f rs-12 muffler. I weighed that amount and put it in but there is about an inch gap of space left. Is that normal or should the whole exhaust be packed all the way to the top?
If you follow the instructions with our repack kit you will know (if its the correct kit) that you packed the muffler to tight. Give us a call if you need help. 800-634-9166
@@YoshimuraUSA Followed your instructions but the thing is you dont sell a repack kit for a 2022 yz250f rs-12. Hard to buy the right kit if you don't sell one. So I was told by your sales to buy a different one that came with 2.5lbs of packing and to weigh out 2.1lbs. Of course this kit also came with exhaust graphics fthat is different and doesn't look the same as the rs-12. No mention anywhere in the instructions about packing it to tight so how would I know if I packed it to tight? After emailing customer support they told me to just add more which sounds like now was the wrong thing to do. Dont know because you didnt answer the question. It would have been nice if you just answered the question instead of implying I did something wrong and bought the wrong kit and didn't follow instructions. Now I am worried it is packed to tight after following your supports advice. So I am going to ask again so if someone else has this problem they will know the answer, is it normal for that inch gap to be there if I weighed out the correct amount?
@@rstephen001 The packing kit that is for your bike is here docs.yoshimura-rd.com/REPACK-RS12-MX.pdf and contains 2.2lbs of packing material as well as hardware and decals for the most current version of your muffler. Note: Your system was originally packed with 2.1lbs of the same material. We do recommend in our instructions to use the whole amount of material which is less that 5% over... This is a negligible difference to overpack and really only adds a couple ounces of weight and increases durability.
From experience we can say its easier to pack a system too tight than it is to pack it too loose. Too loose leaves you with extra material, too tight leaves space when you are done, and neither are ideal. For the best results we recommend you remove the packing and re stuff the muffler evenly adjusting the density of the packing to finish the job with the packing evenly distributed from the front to the back of your muffler's sleeve. Hope this helps.
If you have any other issues please call in and we will try to fly you in for a safe landing...
@@YoshimuraUSA Thank you for the response. Not sure why I was told to buy the adv kit by your sales guy Don then. You also need to update your kits information on your website to show which kit is for yz250f. Currently even that mx kit does not list the yz250f as a bike that the kit is for which I'm guessing is because it technically isn't. It is already put back together so I am not going to rebuy another kit to get new rivets that I would need to repack it again. It would be nice if you sold a kit that came with the correct amount of packing for the yz250f, would have been a lot less hassle and confusion. It seems like the rs-12 for the yz250f was an afterthought with it being literally the only bike that doesn't have its own repack kit and your sales people giving out wrong information on what kit should be used for it.
I know you arent supposed to gut these. I bought a new RS-5 a few months ago. I really love the look and the brand. The sound is good! But a little quieter than I was hoping for. Is there a good way to make these a little louder without removing the packing?
You can remove the sound insert.
I've seen people cut them down in length and put the end of the can back on, it won't be an insane amount of change but it'll be a bit louder.
@@cultofeyes7260 We completely do not recommend cutting your muffler down.
@@YoshimuraUSA naah its a great idea 🤣
Erm, remove the baffle?
Yosh 💪

Can I use aluminum closed rivets on 2 stroke silencer? What is the size of the rivets?
We don't make 2 stoke silencers so we cant say...
@Yoshimura R&D of America, Inc.
In response to another comment you mention that the rivet cannot be properly installed by a hand riveter and can only be properly installed by a pneumatic riveter. Why is that? What do pneumatic riveters do differently than a hand riveter?
A commercial hand rivet gun will work fine… most local hardware stores don’t offer that option and instead sell light duty rivet guns that are suitable for aluminum or small 1/8 “ rivets. If you can manage enough grip strength to pull a 2/16 stainless rivet with a standard manual gun I ihave yet to see on not destroy the jaws by either stripping the gripping ridges or outright breaking the mandrels. The pneumatic guns sold at places like Harbor Freight have plenty of HP to pull the mandrel and are durable enough for occasional use.
@@YoshimuraUSA which brand of pneumatic rivet guns were you guys using in this video? I noticed 2 different types. Thanks!
@@crawfordd17 The brand doesn't matter, the consistency and ease of pulling the stem of the rivet is key.
I have a damaged carbon end cap what do it do ? It’s for a 2014 crf250r
We can fix it or you can fix it. www.yoshimura-rd.com/collections/muffler-end-caps
I just bought the repack kit for my TRS , and I weight the exact grams for my 18” BUT it’s pure white filling and my question is if I putt it in with a screwdriver or can I first wrap it around the metal sleeve first ... Cause there are no videos available of the material that yoshi send over to customers 🤷♂️.
If you take a look at the original filling , it’s prepacked and easy to install , why is that not available ? Much Easyer then a bag of filling material
Yes you can use a screwdriver, but we would recommend something a little more blunt like the end of a broom handle etc.
That packing that was installed back when your muffler was made is no longer available.
@@YoshimuraUSA thanks for the reply but I was wondering if there is a possibility to get in contact with one of tech guys who can assure me that I did it the correct way cause I’m not convinced that it’s done properly , if feel less resistance in the muffler and more pressure but still feel vibration from the aluminium housing when I rev the bike 🙄
@@florrevansteenkiste maybe its better you send to us for repacking...call us 800-634-9166
Do you need a pneumatic rivet gun or can you use a manual rivet gun?
Pneumatic will save you a lot of headaches and is a better tool for the job
@@YoshimuraUSA what about a battery powered riveter?
@@HighGrade_FireBlade never used one.
I'll go ahead and do that myself said no one ever after watching this video 😂
LOL!
Yeah I think I will do it
Easy
I've been a certified motorcycle tech since the middle 90s, and currently own my own cycle repair shop. "I'll go ahead and do it myself." 😁
Can you take the baffle out ? Or the silencer on my rs5
yes! Call us with any questions
Yeah exactly
Does the muffler
Get
Louder if it needs repacking?
Yes it does!
What is average cost to have exhaust repacked by you guys
One MILLION dollars!
I plan to repackaging fiberglass on my yoshi rs-2 on my klx250s...any dealer malaysian that i could refer?
We recommend using only Yoshimura components.
What's the downside to removing all the packing besides being really loud ??? I've ran into a few riders on the streets who removed all the packing out their mufflers left them hollow?
Besides your bike not running right, it being loud as heck and the muffler could literally explode no downside.
Hi for malaysia u can fix it i got 1 exhaust Yoshimura for yamaha 135cc
Hence; a sleeve-- easily gets-- twisted bent vibrato, i.e. reverbs - spider cracks.
I want that dude on the left's hat so bad
Sold out!
How to achieve deep bass sound for mufflers on single cylinders?
Use the Alpha!
Are these road legal from a noise and emissions point of view?
yes.
Rather pay the extra money 💰 and have a professional repack it for me and make sure it gets done the right way.
There ya go!
This is only worth doing yourself if you have the equipment available to use. I live in Los Angeles. No fuckin way I'm doing this at home i wish
Do I have to have a pneumatic rivet gun for this?
Absolutely!
Hell no you don't, manual rivet gun achieves the same thing. Really guys !
@@1kory883 I did mine with a regular rivet gun and hardware store rivets 20k miles ago. No problems
Alright guys, you heard what he said. Rubber side down.
haha!
Does this also go for 4-stroke mufflers?
yes
My wife is going to hate when I show my son how to repack his own, and then mine.
could stainless steel sheet metal screws be used instead of the rivets?
Absolutely not!
@@YoshimuraUSA why is that??
My 690sm Arrow exhaust sounded great - 8k miles later it sounds ridiculously loud and clapped out. I feel sorry for my neighbors in the morning. I'm that guy with the stupid exhaust that sets off car alarms. Moms hear me coming and snatch their children and run for safety in parking lots. Ugh.
Bummer!
you need to pack sum muff
Not user friendly. FMF can be taken apart with common tools.
Definitely dont need a pneumatic rivet gun.
Certainly makes the job a ton easier. Popping the spec rivets need to be tight.
I'm sure everybody has a gram scale
You can use Google to convert the weight...
Why does he look like negan from twd tho lmao
There is absolutely no reason to have rivets instead of screws. The whole idea seems to be an ongoing maintenance cost. Kind of like a membership.
We have been doing it wrong all these years :(
why does that guy look like negan from the walking dead 😂
It's him!
Orrrr, just buy a new one. Awesome video, but guys like me have no time for this shit unfortunately.
I don’t think many people listen to half the shit said in this video
That's for sure! We see a lot of burnt out mufflers that do not get proper maintenance.
Yoshimura R&D of America, Inc. I pulled mine off my fourwheeler and 90% of the packing was gone
@@lucassturgin8710 better repack it or get it in to us!
Yoshimura R&D of America, Inc. I already repacked it
I'm just gonna use screws
We don't recommend that. that will void any warrantee as well.
Do not do this! Once they said remove the rivets I was like wtf you need those there's better videos forsure these guys will mess up your muffler
We have built and rebuilt countless mufflers over the course of almost 70 years in business, interesting we would "mess up a muffler."
I just did 2 of my bikes DO NOT TAKE OUT THE RIVETS
@@codyray8754 then how the hell did you pack it?
@jamesnorth7318 you can get a rubber mallet and you can knock it loose and you slide it back together it's alot simpler than this dude trying to make it.
Just look for another video bc I didn't have to do none of this
