I have noticed a few posts recently regarding 2in1 conversions. I thought I would add my experience modding my '04 XTX with a raptor 700 quad 2in1 header.

The headers fitted very neatly with the obvious problems of the radiator hose, the clutch cable and rear break fluid reservoir.

Re-routing the radiator hose and break fluid reservoir is no big deal, the biggest problem i found is the heat generated from the headers. I.e. Idling for about 2 mins melted the radiator fastening rubbers and any longer, the header would have glowed. With all that soft rubber and plastic around that area, not to mention the clutch cable running very close, I just never had the confidence it would not melt something. I did not however exhaustively look into the heat shield option but I cannot see anything as thin as tape shielding that much heat.

On the plus side, I did go for a short ride once mocked up and the bike went very well - very load tho. I thought that I would have to invest in a power commander but thankfully I did not. The CCC stainless ovals worked a treat and I have the kev fuelling mod so maybe that helped (cheers kev!).

I will probably try again as it can be done without too much bother and I do think it looks the dogs.

OK, just thought I'd share that.
