Product details
This Flow FX cat-back exhaust system is designed for all 1999-2004 Jeep Grand Cherokee models with the 4.0L or 4.7L engines. Features include 409 stainless steel construction for added durability and 16-gauge 2.50-inch mandrel-bent tubing for free unrestricted flow. The compact oval "straight-through" Flow FX performance muffler attaches behind the catalytic converter and delivers a moderate deep powerful sound while the mandrel-bent stainless tailpipe tucks up high in the undercarriage protecting it from being crushed when traversing rocky terrain. The system uses the factory hanger locations and is finished off with a 3.50-inch black ceramic coated 304 stainless steel tip embossed with the Flowmaster name. The kit includes detailed instructions and all hardware necessary for a quick and easy installation you can do at home. Covered by our Lifetime Limited Warranty.
