they are not rusty, they are new so just wondered what best course of action was , prevention better than cause? mind you , as said, at that price I'm tempted to wait until I need replacement and then go for stainless.


Then why not put your standards on ebay while they're still fairly new, then once sold order the stainless?

I'm considering using cure rust on the collector box (if that's what it's called) bringing the 4 pipes to one and then painting this.  I've been told it's this box which is the actual problem and not the pipes which are apparently stainless anyway.

Be careful Midden, if you do this. I did it with rust converter and then granville on it after and the paint fell straight off after 1 ride, reaction with converter. Needless to say I'm redoing mine this weekend in the hurricane!


The collector box and the joins on the balance pipes is where mine rusts.

Thanks for the heads up Nick  Smile

Am I the first to suggest this without fear of being disavowed by the forum for a completely ridiculous idea?


It crossed my mind while reading this thread about whether that stuff used to treat inside of petrol tank would work. Or perhaps ACF50.

It just seemed a good idea as everyone moans that the rust from the inside out on the collector.
When I finally (hopefully many years down the line) replace mine, I'll try painting the inside and let ya'll know.

I sprayed mine.  Looked awesome for about a month and then it was manky again.  I can wholeheartedly agree with using a brush on application instead of a spray.
Opinions are like A**holes, Everyone has one.  Some people seem to have more than one though which is a bit odd.

I painted mine in situ with the belly pan off , two years ago, with granville HT paint , brush on not spray , still looks like new and I live 2 miles from the Sea front , salty roads , bad weather and all that. Defo recommend brush on Granville HT paint or equiv. Just make sure to key the pipes with wire wool - I would not use sandpaper but thats a personal preference.

My collector box had rusted through a touch, only about the size of a 5p, so i removed the pipes and had a mate weld a small plate over the hole, then dressed it up a bit and cleaned the pipes with a wire brush and a final rub-down with fine emery paper.
Bought a can of High temp paint from B&Q, the stuff used for stoves and used all the can on the pipes, the can was good for three decent coats.
Still looking good after six months use, although i do also have a fender defender jobbie on the front mudguard, so that keeps a lot of crap off the pipes.

How did you find the header bolts mate? In term of getting them out without stripping or shearing.  I used two large cans of wd40 spraying every morning and night over the bolts before attempting removal... Not sure if it was necessary though??

I generally use spray stove black on exhaust pipes and every now and then, spray them with silicone.

Sorry for the late reply tweety, to be honest mate, they came off dead easy.....but probably because the cylinder head had been off not long before, to have some work done on it, so they had been copper greased by the guy who did the work.
If i had done them before it went in, i would probably have sprayed them a few times with WD, just to allow for penetration before getting the socket on them.

All okay mate. Apologies... I should have reposted that I got them off by spraying with wilko lube £99p per 300ml. Cheap WD40 subs. All okay. Cleaned and sprayed. Cheers
