how much does a catback exhaust improve hp?

Feb 24, 2010 by jeepster123 | Posted in Jeep

ive got a 2000 jeep wrangler 4.0, ive added a superchip and a KnN high air flow filter and its pretty quick now but i think it just needs a little bit more muscle. any thoughts?

12-20 hp gain sounds about right.. You've done all you can for a small improvement. If you're looking for some big hp gains, think about boosting it or doing some internals.
