Ok this has been troubling me for a while now, it seems like my header pipe start to rust, but its more of a mud burnt onto the pipe.
it all seems to start from the top of the pipe and runs down the inside, most DR fotos posted I see the same thing happening.
what can cause this? leakage past the exhaust gasket???

Mud burns onto the header when it is hot.
Get yourself some Autosol and some elbowgrease. They will look new again.

yes, thanks the plan, just want to find out if theres not something specific that causes this...
I just find it strange where the mud is burning onto the pipe...
it really looks more like fluid running down the pipe, where mud then burns onto it......

The header pipe is stainless. Keep mine clean with some scotch brite!👍

You can polish the (stainless) header but it will go brow after a while again. Oxidation of the stainless steel due to exposure to high temperature and atmospheric oxygen. There is only one way to avoid this: Double walled headers as found on most classic Jap. bikes

Ceramic coat dit. Jy kan dit self ook doen, solank jou vrou jou net nie vang terwyl jy die oond gebruik nie. Dit kan nogal moeilik wees om te verduidelik as daar n exhaust in die oond le.

thanks all, for the advise on how to clean it, but it still does not answer my question:
is this due to some or other leakage past the exhaust gasket or something?
Form the picture you can see it's just on certain parts of the exhaust...
my first thoughts was it was like oil is running down from the top of the exhaust and mud is burning onto it....
if it was just due to heat or exposure, the entire pipe would start to go brown?

hahahaha glo my sal nie die vreemdste ding wees wat sy al ooit in die oond gesien het as sy by die huis kom nie...
ek DIY graag in ding.
hoe kan ek dit self doen? ?

"Also inspect the header pipe for any hairline cracks which cause exhaust leaks."

Autosol and plenty of elbow grease is the way to go.

As mens die pyp afhaal en skoonmaak is daar gewoonlik geen roes om die pyp nie, dis net modder wat 'n baksteen word om jou uitlaatpyp. Die plekke waar dit aanpak is gewoonlik die dele waar mens nie maklik kan was nie.
Op myne was die voorkant van die pyp ook baie meer skoon omdat ek baie sand pad ry en die voorwiel sand opskiet, amper die pyp sandblast.

Ok ek het n foto van die header van n beter angel af, verstaan nou hoekom dit vir my lyk asof daar iets teen die pyp afloop....

so klein bietjie staalwol gevolg deur autosol, maar net op klein stukkie, nog nie tyd gehaad om werklik te doen nie....
plus my autosol applicator wou nie vir lank saam werk nie...

Goeie werk! Lyk netjies!
Asbakkies mooi leeg gemaak!

ja, het ook daai opgelet.
Net jammer hyt nou sy kamera staan en breek

ok, so alles is nou mooi skoon en oppad terug vanaand.
1) Sal julle aanraai dat ek copperslip op die boude sit wat die header pyp aan die head vas maak?
2) Die Splinter nuwe OEM muffler gasket wat ek gekoop het is presies die selfde buite diameter as die FMF pyp, so dit gaan nie werk nie.
waste ander opsies is daar om daai seel daar te kry, het laas gungum gebruik... miskien heat resistant silicon?
