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.

[@makantahi3731]

maybe outer pipe is titanium, but brand sticker adds power and price

[@hazimreitz]

They have to get back r&d cost sooooo....

[@bobz1736]

A before and after sound check would have been good 🤔

[@pdfsbanda8300]

you can use gloves for touch the ceramic woll

[@PaulXchannel]

I normally use it. This type woll does not prick.

[@luigimottiv]

Does the exact same process applies for the carbon fiber version of the exhaust?

[@PaulXchannel]

Yes

[@chadrides914]

Your videos are very satisfying to watch. I really enjoy and dirtbike related content. Thanks.

If you breathe asbestos fibers, you may increase the risk of several serious diseases, including asbestosis, mesothelioma and lung cancer.

[@Anonymouseys]

Surely there is no asbestos in something this modern?

No asbestos here. Here, no asbestos.

Hi, is it true that we must use a specifically made rivet for Akra? or any rivet works fine?

[@Cocoe56]

can i use a gypsum ceramic knauf

[@johnmdc4228]

very dangerous for not wearing gloves and mask

[@guitojs]

Doesn't the rivet need to be "blind"? Did you experienced any leaking trough them?

[@PaulXchannel]

Tear rivet is blind !

[@guitojs]

@@PaulXchannel yes I saw it. I can't find blind stainless steel rivets with the correct size (4.8x9.5mm), only aluminum.

Great video. What was the tape you used to wrap around wool? Just a regular tape or specially made for high temp aplications?

[@PaulXchannel]

Use ordinary tape or thread. Over time the tape evaporates.

[@Keith-l2s]

Great clip. The only thing I'd add is that I wouldn't be using sellotape inside the can. It'll burn out very quickly and leave the wool loose which in turn will lead to premature failure. Consider lockwire as an alternative?

[@PaulXchannel]

The tape is only for insertion.

[@Keith-l2s]

@@PaulXchannel Agreed, but you need the wire or stainless mesh around it to prevent the wool from breaking up. Sellotape will just burn away and allow the wool to become loose.

[@Bushrookie820]

Got the same exhaust it's impossible to find spare parts

[@Peter_Grekov_91]

Ye ok so much plastic tape haha and the exusht can't take breath

[@vineettyagi7973]

using plastic tape? seriously?

[@fedsiamanna]

I did the same and now wool comes out as the same as you, then stop throwing wool out?

[@J-F01]

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

[@DonGH297]

Then you probably changed it too early? Or not enough wool?

[@J-F01]

It didnt have any wool before. And I put it in quit alot

[@hvhnubek]

glasswool dimensions please?

[@Teamster542]

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.

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.

I don't think 1 package will be enough. Buy 2 pieces instead and press enough.

Is that a 2 stroke? What's up with the smoke 🤣

Hey man, cool video. By the way whats the purpose of repacking the exhaust muffler?

[@PaulXchannel]

Sometimes it is empty or only half full. Exhaust fumes destroy it.

[@jand.265]

Hi. I suppose the FMF (which is clearly cheaper) wool is equally good in quality?

[@PaulXchannel]

Yes

[@cristianarad6637]

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!

Something with pressures and power.

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]

Are these the shiny looking ones? Or steel wool?

[@hodaka1000]

@@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
