Realistic heat weathering on exhaust headers?

I have just started the construction of tamiya’s Ferrari F50, yellow version. I would like to replicate the look of the exhaust headers having been under extreme heat. I have seen it done but don’t have a clue how to do it. If anyone could please let me know how!

Many ideas on this technique would be appreciated!!

Thanks markiii, that link was very helpful.

No problem, they also have one of the howto’s on cars, in case you did’nt see that link.

Good Luck
