Rub it down and rust treat it (if its bad enough to need it). You can then get heat resistant black paint to repaint the exhaust.

Trixie's advice is fine, but you can expect to do it every year. Once your mild steel exhaust starts to rust, it's a slow death for it.

Simply put, the only stuff that will stick to it is high temp paint. The only way you will get the exaust clean enough for high temp paint to work properly is to get it shot-blasted, and if the exhaust is a few years old, that'll put holes in it.

So, in my opinion;
1. Spanking new stainless pipe. Lovely.
2. Quick razz with a wire brush on a drill, mop on B+Q BBQ paint, repeat next year. Use more expensive paint if you want, but it'll still end up on the floor. Less lovely but considerably cheaper.

I had an exhaust delivered to me once and there was a note in the box saying that the paint on it was "for cosmetic purposes only", so
I managed to save that one by stripping and re-painting it properly before any rot set in.

sadly not any more! use to be a welder and there was a whole massive workshop for sand blasting! used to make pontoons and boats etc. I never did anything myself in there (blasting) but i got a bloke to to my old bmx frame! it left it really rough!!! that stuff would deffo blow holes into it even though it is just surface rust. would be nice to get it blasted but im really paranoid that if i do and it does produce loads of holes, that i wont beable to get a new exhaust!!!

i cant find a new/second hand 1 anywere!!!!!!!
i dont mind how much it cost!!!!! (to an extent)

think i will have to stick with the brush and paint idear and just keep ontop of it!

loply - 2-3 years from new, and with a light grit, I'd think no problem at all. Much older that, the combination of internal and external pitting turns exhaust downpipes into teabags.

If you're never blasted through rusty sheet steel, you're really not trying hard enough.

I would just wire brush the rust off clean it all up prep it nicely, treat any bad rust then paint it with either wilkinsons BBQ paint as from my experience it is by far the best or use blackboard paint which is a bit of a bugger to use as you have to paint it on whereas the BBQ paint sprays on and gives excellent results

bbq paint it is then!!!!

thanks every 1!!!!

but what is the best treatment to use????

In my opinion, don't bother.

1. If you put a chemical treatment on it, and then paint over the top of it with heat resistant paint, then there's a very good chance the chemical stuff will react with the heat and lift off the paint. That's why the surface must be immaculatly clean (blasted/new) for high temp paint to work right.

2. Given that you'll never get it clean enough, and you'll be doing it again next year anyway, save yourself the 6 quid the treatment costs.
