"I installed the K&N 63 series along w/Gibson Exhaust. Definitely not the same Jeep Renegade, it's like a Jeep on Steroids. The pickup is phoenominal, but the exhaust in cab noise is loader than I thought. I have kids and a wife so, I'm a bit more reserve when it comes to load noise, but I do love the performance and the noticeable difference on gas (chaachiing!!!)." —Jamie A from Pueblo, CO bought a Jet Performance Module for a 2004 Jeep Liberty.
