I am sure that the headers I have are stock.

I have ordered some heat wrap for the headers and heat shield for the hose and clutch cable. The guy I spoke to assures me that the combination will reduce the heat seep by 95% - should be no problem then.

I will post updates.

Oh and another thing rudiedj, if you need a good guy in Cape Town, let me know. An old school pal of mine specialises in XT's and thumper's. He is in Table View. He's the guy that sent the headers...
