The X-pipe balances both sides of the cylinder banks. The factory H bounces off each other making back pressure. In-turn the X will lose a little low end but pull harder in the upper rpms. The H is better for low end thus creating back pressure. IMO getting rid of the H is by far better. Yes you lose back pressure but you'll feel the gains up top.
