mild on 'Ace, s/s on FZR?

I read somewhere that the FZRs headers are stainless, apart from the cast exup housing.
Is this correct?

I ask as I've a world of remedial work to do on my Thunderace header set and on't want to ditch the exup.

Cheers guys.

yes the FZR front pipes are stainless until the cast steel collector where the valve fits.

The FZR headers will fit the Ace but I believe the rad may have to be spaced forward slightly at its lower edge

FZR headers.......

Not too bothered about moving rad a touch, but I do have one more thing.

What years/model Fzr wore stainless pipes as a quick ebay browse saw either mild headers or stainless headers with no exup housing.

Thanks again in advance

as far as I know all 89-95 FZR headers are stainless. Some that you see on Ebay are seriously neglected and will rust (some grades of stainless do that, others dont eg marine grade)

The stainless headers without the housing are aftermarket manufactured

Then theres the ace headers with the link pipe incorporated as opposed to being part of the end can like the FZR

I've also seen a few FZR headers with a seriously large exit pipe like the one in the image below. As far as I know theres are headers thats been altered at some point in time when the take off pipes rot (as many tend to...like the one I have in the workshop at present. That one will be replaced as original tho')
