Jeep is 195 HP at the crank...the throttle body spacer really wakes it up and helps with fuel mileage so the air doesn't have such an abrupt turn into the engine. The header gets rid of the dual exhaust manifolds that are notorious for cracking and helps with flow. The rest of the exhaust isn't too restrictive. You can do some PCM work and have it to about 250-270 crank horsepower pretty quickly. But Jeeps are meant for offroad...not banging your boyfriend. So throw some mudders on it and a lift.
