    Phone these chaps - looks like they have experience. Post if they have a copper alternative.

    that maybe the case on brand new pipes with a thou or so of copperflashing, this has seen thirty years on a bike so some of the pits are quite deep.

    What gauge were they made from originally ? 16G is marginal for metalspraying and anything thinner, forget it.
    IMO you may just have to face up to gas welding a heap of pits followed by file/linish and pro polish.

    Remember, you'll only do it once.....

    Would ceramic coating the inside of the pipe help - I know they say a full ceramic coat inside and out can drop the surface temperature up to 50% not sure what the drop would be just coating the inside of the header?
    I love the smell of twin V16's in the morning..

    now there's some thinking, just wondering about how it will coat on an old rusty surface...

    Before they put it on they blast it a bit to aid adhesion. I stripped the HPC coating off some pipes & found they needed a bit of a sand before I sprayed them. Not sure how they would do the inside. Also not sure how well it would hold onto inside of square pipes, if you ran the blaster down there, you'd miss heaps.

    They will need a severe acid to remove the rust & old chrome, that will leave a depressing surface. From there I guess its hard work, but probably your only option.
    Don't you look at my accountant.

    One could always make a new set I guess - fresh metal to chrome.

    Might be harder than you think, have you seen the pipes he's talking about?

    I suggested the same. I have seen the pipes, and Steve Roberts himself said it was the biggest job he'd ever done (or words to that effect).

    All made out of flat steel, insane! But modeling the pieces first would reduce the work by half.

    Most chromers won't touch a used set off pipes as the carbon from the pipes will contaminate there baths.Mt Eden electroplaters were good and used triple chrome since they did alot off bumpers back in the day.Till they are completely stripped and all rust removed to inspect if they are recoverable.
    Best is to give the pipes to a Good radiator shop for them to cook out the rust and carbon build up and then see where you stand and to see if you have a good amount off metal to play with.
    Im sure there is someone local that has a mandrel bender that can laser measure them and bend them up pretty cheap.
    Building pipes aren't that hard once you've done a few here is what i finished on monday a 6-1 cbx in stainless

    that looks nice. real nice.

    But how many have you made using square tube? Why would you? Well that's kinda the point

    Well if it is square thats even easier as you could just find someone with a rotary draw pipe bender there must be plenty off these units around and will give a nice bend.
    Early years off indy cars (cosworth) they tried square headers to squeeze the shape off the exhaust wave but it never took off.

    The original pipes were made from sheet, and made by hand quite painstakingly I imagine. But aesthetically they would look the same to make new ones the way described.

    You know about this Spyda?
