Will an 01 yz450f pipe bolt to an 06 head??

I don't care that the bend is wrong, I only care that the exhaust pipe is the same diameter and bolt flange is correct and it will bolt to an 06. Anyone know??

Thanks.

So is this a big bore? Didn't know they made 450's in 01

450 came out in production in 03

OK it must be a 03 then. Will an 03 pipe bolt to a 06 head??

Thanks again!!

Are you sure it isn't an 01 YZ426F, the 450's predecessor? The 03-06 YZ450F use the same head pipe, I'm not sure if a 426 head pipe will bolt up though.
