This Flowmaster® Flow FX cat-back exhaust system is designed for 1997-1999 Jeep Wrangler TJ's with 2.5L or 4.0L engines and features all stainless steel construction for added durability and longevity. The 2.50-inch Flow FX® "straight-through" performance muffler mounts high in the frame rail just behind the factory catalytic converter and has a moderate deep powerful sound. The 2.50-inch mandrel-bent stainless steel tailpipe is tucked up high in the undercarriage protecting it from being crushed when traversing rocky terrain. The system is finished off with a large 3.50-inch black ceramic coated stainless steel tip embossed with the Flowmaster logo. Uses the factory hanger locations, comes with installation instructions and all hardware necessary for a quick and easy installation you can do at home.
