Huh? Are you talking about a header? I'm talking about the cylinder head.

I think nothing. The compression is the same I think. Wait, maybe not. Besides that the ECU tunes everything in the HX for better mileage instead of power.

I thought the EX has slightly more compression, but it wouldn't suprise me if they are the same.
