Is it time to replace your old factory exhaust or are you looking for an aggressive sound to match the look of your Jeep Cherokee XJ 4.0L? This is the kit for you. This kit features an aluminized 2.5" mandrel bent rear exit tailpipe for maximum flow and a unique exhaust tone. With our kits you get the quality, look, sound and performance you are searching for at an affordable price! Please note: This system is designed to replace your factory OEM exhaust starting from the inlet of the muffler back. YOU MAY NEED A DIFFERENT INLET ADAPTER DEPENDING ON YOUR EXISTING EXHAUST. If your exhaust has been replaced or modified previously fabrication to the existing exhaust on your Jeep may be necessary for the proper installation of our kit. Jeeps with modified suspension or body lifts may also require fabrication of the exhaust or vehicle for the proper installation of our kit. This kit is ONLY designed for 4.0L models.
