Product Description

The MBRP S5510409 is an Armor Plus series cat-back exhaust system for the 2002-2007 Jeep Liberty equipped with the 2.4L I4 or 3.7L V6 gasoline engine. Built from T409 stainless steel with fully mandrel-bent tubing, it replaces the restrictive factory exhaust from the catalytic converter back, maximizing exhaust flow to free up horsepower and torque. The Street Profile muffler delivers a deeper, more aggressive exhaust note under acceleration while remaining composed at highway speeds -- no obnoxious drone.

Installation is a straightforward bolt-on using the factory OEM hanger locations -- no cutting, welding, or modifications required. All necessary clamps and hardware are included in the box. The polished T304 stainless 3.75" single wall rolled-end tip completes the look with a clean, finished appearance. MBRP backs this system with a Lifetime Warranty. Note: does not fit 2005-2006 Liberty models equipped with the 2.8L CRD turbodiesel engine.
