Maybe with removed cats, a catback exhaust, bigger intake, Dinan throttle body and software tune for it, you might gain 10 ponies or more.

NA motor performance mods are always more expensive and yield very little gains until you start doing cams and the like. I mean even an engineered catback like Eisenmann I think might advertise a gain of 6-7 hp? And thats over 1k just for the exhaust.

Not to mention the o2 sensor spacers you'll have to install to keep the CEL away, IMO I wouldn't remove the cats.
