uncorrected: 239.6 hp @ 5436 rpm, 256.4 lb/ft @ 4037 rpm.

The car doesn't really feel any different without the cats, but it sounds way more badass now

Keep your cats intact. You'll keep the air clean, keep yourself smelling clean, avoid possible and expensive fines(if caught of course), and retain your low-end torque.

WOW, that torque seems WAY low. What are your mods? My bolt-on 93 LX put down 202hp and 268lb/ft. I just have underdrive pulleys, high-flow cats, and a mac cat-back.

The sound is awesome. Just put on BBK headers, OR H Pipe and
Flowmasters with a Moroso air filter. I will be waking up neighbors.
