Hi. This video shows - step by step - Repack of motocross exhaust muffler - KTM SX-F 450. . . . for more interesting videos click ,, HERE " / @paulxchannel
When you see the inside of an exhaust muffer you will immediately notice that such simple machanism and minimal parts s of a muffer don't worth its insanely expensive price tag.
Awesome video. Thank you. Question, what size rivets? I have an FMF Powercore 2 (So Cali) silencer for my sons 2019 TC65 and the rivets look pretty big.
Nice video thank you i will apply in my exhust to put new cermic woll. Just want to ask how many years to replace the ceramic wool of akrapovic exhust.Thanks a lot
@@PaulXchannel my aprilia 2013 and 1st owner change it to akrapovic exhust already more than a year and i dont know if need to replace the ceramic wool.
Good work...!Have a question....What is that metal cylinder for,over the hooled part?Sound damping is much better without it..I use those dishwashers,mettalic,well packed and pressed...I use mineral or synthetic wool,only for city motorcycles,where there are another rules for noises..:-))) I follow you whit great pleasure,and I wish you al the best from ARAD/Romania!
Fiz isso na minha SXF350 mas arranquei a tela de arames de aço e coloquei la de pedra enchendo com lá a parte superior iguaizinhos a moto ficou uns HP a mais porém o som ficou um pouco mais forte porém suportável para a pista de Cross 😜
Did you see it has three holes at the front of the exhaust? I did mine yesterday an air was coming out of those holes, do you know why those holes are there? An it's purpose?
I use stainless steel washing-up scourers not the wool ones but the heavy reusable ones, they're always available locally they cost next to nothing and they work well I buy packs of three and will generally use seven or eight they open up like a donut and you slip them around the baffle pipe My muffler has a bolt in baffle and I change them each year I suggested it to a friend recently for his dirt bike with a similar riveted muffle and he didn't have a problem with it
@@Drt0Kkdo The very heavy very corse stainless steel ones without soap, you'll find you can open them up like a donut and fit them around the perpetrated pipe inside the muffler, I use about seven or eight of them lined up alone the perpetrated pipe, my muffle is a traditional "Dunstall" style with three small bolts that hold the baffle in from the back end of the muffler I suppose if your muffler didn't use a perpetrated pipe you might fill it with the same things but you could try stretching them out more so they weren't packed to tightly and I'd be changing them more often if that was the case So not the fine steel wool or stainless steel wool with or without soap that will usually come in a box of ten or fifteen but the very corse stainless steel ones that you'll usually find in a packet of two three or six at supermarkets Or at least you find them here in Australia at any supermarket Coincidently I was about to go home and repack my muffler today, it's that time of the year again and I've got it dismantled and polished up and ready to reassemble with new ones waiting to put back in it when I get there
@@Drt0Kkdo ... I thought of it myself, but soon after I first used them I saw a fella somewhere who was restoring a Jaguar and another fella who was helping him got him to use the same things in it's muffler
@@Drt0Kkdo Home Because it's near ready to assemble I might make a video on it and post it on here tomorrow I want to paint the baffle and inside the back of the muffler where the baffle fits into it with heat proof paint and I've still gotta cut it's gasket and buff the stainless steel bolts that retain the baffle before I assemble it but that won't take long
@@hodaka1000 can you give me the specific product you used so I can look for the similar product locally? There might be a chance I already own a bunch under our sink lol.
Hey, does anyone know what the rod on the inside of the exhaust that you wrap the fiber around is called ? Mine has become damaged and isn't as long as the one in the video. Can I get a replacement of it from somewhere? I have almost the exact same exhaust.
nice video! i bought a cheap replica for my bike and after just a month it started rattling probably due to bad rivets. I might need to open it and put new rivets in...

Very nicely done bro .Good work
Really useful video.
Nice video, thanks
Thanks man ❤️💪
Hi, is it true that we must use a specifically made rivet for Akra? or any rivet works fine?
Cracking video, ta

s of a muffer don't worth its insanely expensive price tag.
maybe outer pipe is titanium, but brand sticker adds power and price
Great channel 💪🏼
Great video. What was the tape you used to wrap around wool? Just a regular tape or specially made for high temp aplications?
Use ordinary tape or thread.
Over time the tape evaporates.

Size - 4.8mm
A before and after sound check would have been good 🤔
Nice job there. What length rivets did you use? Thanks
1cm
Nice

It depends on the run of the engine. Approx 80-100 hours
@@PaulXchannel my aprilia 2013 and 1st owner change it to akrapovic exhust already more than a year and i dont know if need to replace the ceramic wool.
Does the exact same process applies for the carbon fiber version of the exhaust?
Yes

Something with pressures and power.
you are new in exhaust, if you would not installed inner perforated pipe , glass wool would last one rewing
Doesn't the rivet need to be "blind"? Did you experienced any leaking trough them?
Tear rivet is blind !
@@PaulXchannel yes I saw it. I can't find blind stainless steel rivets with the correct size (4.8x9.5mm), only aluminum.
Can I order this in Lazada or Shopee? The wool?
Where can i buy the bolts tool
you can use gloves for touch the ceramic woll
I normally use it.
This type woll does not prick.
Hi. I suppose the FMF (which is clearly cheaper) wool is equally good in quality?
Yes
Hey man, cool video. By the way whats the purpose of repacking the exhaust muffler?
Sometimes it is empty or only half full.
Exhaust fumes destroy it.

apparently for mounting a DB killer
I use stainless steel washing-up scourers not the wool ones but the heavy reusable ones, they're always available locally they cost next to nothing and they work well
I buy packs of three and will generally use seven or eight they open up like a donut and you slip them around the baffle pipe
My muffler has a bolt in baffle and I change them each year
I suggested it to a friend recently for his dirt bike with a similar riveted muffle and he didn't have a problem with it
Are these the shiny looking ones? Or steel wool?
@@Drt0Kkdo
The very heavy very corse stainless steel ones without soap, you'll find you can open them up like a donut and fit them around the perpetrated pipe inside the muffler, I use about seven or eight of them lined up alone the perpetrated pipe, my muffle is a traditional "Dunstall" style with three small bolts that hold the baffle in from the back end of the muffler
I suppose if your muffler didn't use a perpetrated pipe you might fill it with the same things but you could try stretching them out more so they weren't packed to tightly and I'd be changing them more often if that was the case
So not the fine steel wool or stainless steel wool with or without soap that will usually come in a box of ten or fifteen but the very corse stainless steel ones that you'll usually find in a packet of two three or six at supermarkets
Or at least you find them here in Australia at any supermarket
Coincidently I was about to go home and repack my muffler today, it's that time of the year again and I've got it dismantled and polished up and ready to reassemble with new ones waiting to put back in it when I get there

Hey Nice video. Did it make a lot of difference before and after. I Just repleced on my and it didnt make a lot of difference
Then you probably changed it too early? Or not enough wool?
It didnt have any wool before. And I put it in quit alot
I have 350 excf and no where does it tell me how much packing I need. I was told it matters ? Any ideas as to how much?
I don't think 1 package will be enough.
Buy 2 pieces instead and press enough.
I did the same and now wool comes out as the same as you, then stop throwing wool out?
Db killer available for this exhaust

how many months to change the ceramic wool???
Approx 80-100 hours
glasswool dimensions please?

👍
Give the spark arrestor a clean with a dry brush next time
Ok
Size Rivets?
Hi, how often do you repack a muffler?
every a yr or so
Got the same exhaust it's impossible to find spare parts
why did you put two more pieces on top?
Notice the shape of the can. It’s taller where he added the extra.
i hope that you can see my comment asap
is it ok if I fill my exhaust with too much material inside?
No problem
What’s the exact name of this muffler?
Come on Gavin.
Is that a 2 stroke? What's up with the smoke 🤣
Вы надеетесь, что скотч сгорит?
Yeah it will burn and it wouldn't be an issue
What's liquid youre using to clean?
machine cleaner - Fleet Star

Hi.. Can i know the rivet size?

is it original Akrapovic?
Yes

don't touch glass fibers whit hands!!
This type of fiber is not aggressive towards the hands.
Of course gloves and goggles must be worn.
And use Aluminium rivets, not stainless! they will rip your aluminium/titanium "tube" when vibrating!
From experience: Aluminum rivets do not have a long service life.
@@PaulXchannel which materials are the original rivets made
I don't know .
Titanium ?
@@PaulXchannel propably a water/gas leak resistant 7075 aluminium rivet

If you breathe asbestos fibers, you may increase the risk of several serious diseases, including asbestosis, mesothelioma and lung cancer.
Surely there is no asbestos in something this modern?
@@Jesus_Iced its fibre glass not asbestos 😂
No asbestos here. Here, no asbestos.
using plastic tape? seriously?
Ye ok so much plastic tape haha and the exusht can't take breath
Lol KTM.
no need to repack, oem fill looks good and better than this raw glass fiber that will evaporate after 3 months
Thats why you put rock wool(mineral wool).
Skip that stupid music, and explain what You're doing in stead.
