Would there be any point in trying to contact the distributors or would that be a waste of time?

It couldn't hurt to contact them. I suspect the damage was caused due to the packing being moeg, but I'm definitely not an expert.



You might have a point.
It seems to have a heat induced discoloration at this point..
A neglected exhaust definitely runs hotter


Doubt agents will warranty - clearly well used. Typical vibration stress fracture and denegration. Carbon end caps are available but get the Vaseline out (even on evilBay they are $$$). The discolouration is normal for titanium. I would suggest either sourcing a trashed can for harvesting the tailpiece - a very tricky weld on TiT thin and on a bend but you may find a wunderkind who can do it. Then trim 10-15mm off can (may need to also shorten the perforated through pipe the same) and re-drill and re-rivitt with SS rivitts after a repack. I am sure Scortch or one of the other local zorst guys would do it for you.

Not what you would expect from "premium brand " slip-on after 13000km.

From the distributor:

With the next system you purchase ensure you re-pack the silencer often this is one of the biggest contributing factors to the rivets and end caps coming loose. What happens is once the exhaust wool is burnt away the damping it offers is no longer there and this then starts adding more vibration which will loosen anything.


Spoke to the OEM DEPT Akrapovic KTM at the Factory and they recommend the packing is changed at a minimum of every 6000km for average use. The Dakar bikes get changed for every stage to ensure no failures may occur which can cost them overall positions. Many things on bikes today require periodical checking to ensure they last...


Does that apply to all their products? Should I be doing the packing on my 2 1200's??

The big singles are very heavy on packing. 2 cyl + much less so. Or thats how I understand it

Dwerg, have you got the Wings yet? I have ordered one and if everything goes well I want to install it on Saturday.

If you've got it, did you do the 15 minutes idle procedure after the install? Ta

Haven't had time to get to the bike yet. A bit busy at work at the moment. I am going to install the stock pipe for the time being

Ended up installing the stock pipe. Just started the bike and rode to work without any idle procedure and it ran fine. Intake noise is now louder than the pipe but it sounds quite nice actually

why don't you have a new stainless steel cap made just shorten the slipon a bit before fitting it
Something to think about...
When you complain, you make yourself a victim. Leave the situation, change the situation, or accept your it. All else is madness.

There must be some truth in this. Have done 60 000km on my Wings with zero issues. I am not aware that I should do packing at any stage.
May the bridges I burn light the way...
