X pipes don't add rasp. Running an or pipe, be it x or h, with imitation mufflers aka glasspacks like stingers, lm2, lm1, magnapacks are what causes the noise he's getting. Cats will help, but not as much as a muffler with packing will. Cats will take the majority of the rasp/blat sound away from inside the car, but outside it's still a blatty noise from 2500rpm and up if you're giving it more than 1/4 throttle. I learned that watching my car get dyno'd years ago. I thought I had cured the rasp with cats because it sounded better from my point of view behind the wheel, but being outside of it that wasn't the case.
