Or a set of stock ones. I wouldn't try and fix those...
Got the header off after Thursday's excursion.
O2 sensor cracked completely off!
Reckon this is fixable or do I have to start looking for replacement headers?

Now the second part of the dilemma...getting it cheaply in South Africa (where our exchange rate is 10:1 for Rand:US$) :(
Damn thats pretty bad. If you cant afford a new one, that could probably be welded. I would just be sure its done by someone that knows what they are doing due to the crack being so close to where it bolts to the head.
it can def be welded, but find a good welder....
Needs to be cleaned well and then make sure the inside gets purged when it's tig welded back together. It's fixable. Switching to XB12 headers should get a small boost in performance, so if you don't have a good welder available, go that route.
Thanx guys! Would looooove one of your headers Dean, but it would be more than a year of saving...
Our exchange rate kills us!
Took it in to the guy that did the Yahweh bike exhaust.
He reckons an easy fix and shouldn't cost more than R150 (US$15) to fix.
Apparently quite a regular sight on the KTMs and I shouldn't feel left out.
He has fixed heaps of similar happenings.
Feel bit more relieved! ;)
its weldable but the metal gave up there due to heat, vibration and decay. especially as it was cracked already.. it didnt happen instantly. that damage quickly escalated when it first cracked then the air leak it created acted as a welding cutting torch to further destroy the metal.
Its heavily carbonized and will fail again if you dont significantly re-inforce the surrounding metal. Just like on many british bikes or older Harleys,, fenders fatigue and crack from the vibration, you can weld them up and they crack again next to the welds partly from the heat affected zones of the welds as well as being fatigued to begin with.
Ever take an old piece of thin metal, bend it back and forth over and over? eventually it work hardens and breaks or cracks. same principle on the old fenders,, but the exhaust pipes are even more brittle basically being next to a torch flame for many miles,
All part of the design, You might note that very few production cars use thin wall exhaust manifolds or headers, most use a thick wall cast iron, the reason is for every moment of operation its degrading, and wearing away. In the service life of a car, thats factored in and often exceeds the life of the car. Thin wall header pipes never live long and prosper UNLESS you have them ceramic coated,,, it acts as a barrier and shield therefore extending the life quite a bit. You will notice yours cracked and broke on the rear cyl where the temps are highest. and the least amount of cooling.
this is a concept the header wrap guys just simply dont comprehend or acknowledge,
Understood, but it is my only option for now.
I am getting it ceramic coated as well.
It will buy me some time to save up and be able to continue riding.
