Few things there I'd like to correct and address. The FI tdx is not a full width x pipe. The mixing area is quite small, maybe .75-1" x 1.5-2". The power difference between H and X pipes is negligeable, with a x pipe edging out an h pipe in peak hp, but an h pipe edging out the x in torque. Typically, X pipes are raspier, h's deeper. As for the angles and amount of bends, they are virtually identical. Flex pipe, got me there. However so long as the inner diameter is 2.5" there should be little to no impact. Further, hks offers better ground clearance, as well as a different decel 'hiss'; It's more muffled. I didn't say I wanted to buy anything, but that I wanted to hear it.
