'06 exhaust header the same as '07-'09's?

I cracked the exhaust header on my 06 YZ450F. I have the stock header with a ProCircuit slip on. I looked around for a replacement head pipe, but I see mostly 07-09's listed. Will one of these fit on my 06? I'd like to just find a cheap replacement OEM takeoff.

The '07 OEM header might fit your PC can, but the '08/'09 won't for sure. For '08 Yamaha went with that crap shorty exhaust and enlarged the header.

I think you need an 06 if the can is specifically made for the 06. Looking at the inserts that came with my fmf silencer the 06 and 07 diameter seem to be quite different.
