Exhaust rusting - can I paint it?

Hi,

My exhaust is rusting to fuck with new holes appearing daily.

I'm beginning to think it's only a matter of time before it snaps in half.

If I sanded it down and painted it with black BBQ paint would this help stop the rust for now?

Cheers.

I doubt it, Alot of the time exhausts tend to rust from the inside anyway.

What bike is it?

Eliminator 250.

What are the chances of a can off a different bike fitting?

It's basically the whole thing from where it connects to the bottom of the engine back.

I think the manifold is OK luckily.

The can is nice and shiny but the pipe leading to it is what's buggered.

If there's holes already, it might be too late for paint.

You might be able to weld it, if not then get your vernier calipers out, measure all the diameters and get onto ebay asking sellers of cheap used similar (ie. Jap cruiser) pipes for the dimensions. Thumbs Up

If you dont mind a bit of a lash up, You can measure the external diameter of the pipe work. And go to your local motor factor. Buy a length of pipe with the same internal Diameter, As the external on your current pipe work. Cut the rusty section out. And sleeve the gap with the new pipe work.

Cut a slot in either end of the new pipe and clamp it.

The length of pipe wont cost more than a tenner. And you will get some clamps from your local Kwik-Fit for next to nothing. Just give one of the lads a couple of quid.

Trouble is that most of the holes are right on the join where the pipe goes into the can.

I could weld a whole new pipe onto the can, and bend it to the right shape, I suppose... (except I don't have a welder, or any skill).

Usually the downpipes are the last thing to rot, the first thing is the collector box and that is the hardest to bodge. But as already said they rot from the inside out so no matter what you do to repair it your going to have to replace it in the end.

Best thing to do is buy a new system then you can fit and forget it.
