MOTAD Header Question

Hi VFR's

Can anyone tell me if there is any difference between these two Motad header models for the 5th and 6th Gen VFR 800

Are the exactly the same but different model numbers? ARe the 98-01 pipe diameter larger?

Any info would be greatly appreciated.

I'm very interested in this question, as I see David Silver has the 98-01, but not the VTEC model. Is there any reason I shouldn't get the 98-01 for my VTEC?

Don't the pipes for the rear cylinders cross over on the vtec model.
