if its one of those cats that is built into the exhuast manifold, removing it will help the entire powerband. if its the one that is located just behind the firewall, then you wont notice any gains, possibly some loss in the low end. i'm speaking from experience, on my dad's 98 civic DX coupe, it had the kind of exhaust manifold with built in cat. one of the runners cracked, so we took it off and replaced it with a 4-2-1 header i bought off of ebay. car got louder, and pulled harder through all the rpms also, went from 32mpg to 34mpg(he drove 80 miles a day round trip to work) since i took my cats out of my wrx, i have noticed slightly better mpg. not that i am technically getting more per tank, its just that i push the car a little harder and still get the same milage. i gotta drive a good 150 miles tomorrow, i usually got 27-28mpg on the freeway, i'll see what i get tomorrow. -------------------- 1994 Celica GT4 WRC Edition
