He definitely didn't lose any power
. While your understanding of the funtion of X and H pipes is correct, you are not taking into consideration the removal of his primary cats. The power impact of removing the primaries will trump the power reduction of the missing x-pipe any day of the week. Not only are they 400 cell, but they are "crushed" to increase ground clearance. For this reason you see a lot of cars make great power with just the primary reduction (leaving the secondary 400 cell cats in place).

Along with a MUST with high revving. never the less, congrats on the purchase.
