An open cutout provides greater peak hp and tq figures. What happens, however, is that the tq peak shifts upward in the rpm range, thus making the car feel sluggish on the low end, when in fact, you have a faster, more powerful car (by a few ponies on a stock setup, and by up to 20 ponies on a modified internal setup which is choked up by a stock or crap catback).
