Akrapovic damage - 690
« on: September 28, 2015, 10:15:56 am »
Hi, has anyone seen this before? Pipe was fitted from new. The bike has 14000kms on the clock and I don't recall any noteworthy  damage from tumbles. Carbon tip also obviously came off

Looks like stress cracks? maybe to much movement on the pipe allow for to much shaking....

Have you ever repacked the exhaust?

Had a similar issue with a Wings, the endcap was still perfect but the can itself had a small part missing and the holes was very big. Seems like you need to repack every 4 000 - 5 000 km

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

It's definitely worth a try.
There's no apparent impact marks on the exhaust which could have lead to this stress fracture:


IMO it's this crack that caused the failure of all the other parts.
Let the good times roll!

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.

If I had to take a guess, the rivets were slightly loose, causing the end cap to vibrate back and forth enlarging the holes and causing the crack

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

My own experience with a 690 seems that everything at the back of the bike/tail piece breaks.Its seems there is a high degree of vibration.
The indicators last a couple of KM's then break off.
My touratech carrier broke(cracked).....Touratech replaced it as a goodwill gesture.

I see your exhaust seems to be a similar problem being a high frechency problem.(my 690 was a 2014 model)

Just a thought

Well by the time we took the end piece off, most of the packing had been blown out so it's hard to tell which came first. The rivets were definitely loose and the cap was rattling around before the crack appeared (or before I noticed it at least)

I also noticed that some of the rivets were loose and later on the entire endcap started coming loose. The 690's are notoriously heavy on packing.

Hope you can make a (cheap) plan. I ended up replacing mine with a very good second hand unit.

Thanks it's beyond repair I'm afraid. I'll see what the distributors have to say and take it from there

Good luck :thumleft:. The wings is a good product, mine lasted around 42 k kms and I did neglect the packing since taking ownership.

Shot I already decided that Wings would be the replacement, it's just a matter now of who's going to pay for it  >:D

I do still have the unused stock pipe and I'll probably fit that for the time being. Hideous freakin thing though

OEM exhausts have metal baffles etc - that tend to last the entire life of the bike.

After market exhaust use packing that needs to be repacked every xxxxx km, I just repacked my Dakar's Van Der Linde exhaust this weekend.

My first packing only lasted about 20 000km my last packing lasted about 30 000km and was still in pretty good shape when I replaced it - it is important to pack it correctly, then it lasts otherwise it gets destroyed quickly.

My Wings did almost the same.  Extreme heat due to packing blowing out after last year's Amag.  I cut it shorter just short of the holes.  Cut inner perforated pipe same amount.  Repack and go. Difference is my end cap did not break, just the titanium skin.

Running at full taps took the packing out in 3 stages. This year I used an FMF.   Sounds kak, fitted extremely poorly, but survived with the packing intact.

Die ou wat ons gehelp het het die kraak probeer weld en die eerste keer wat ek hom start toe blaas daar 'n gat so groot soos 'n 5 rand in die end cap. Het daai oplossing oorweeg maar die end cap is ongelukig Mike Tango
