Description
Overview
The Flowmaster Flow FX Cat-back Exhaust System is a complete, bolt-on upgrade engineered specifically for 1997-1999 Jeep Wrangler TJ models equipped with the 2.5L or 4.0L engine. Built from all stainless steel, this system is designed to deliver lasting durability, improved flow, and a deeper, more assertive exhaust note without the drone that comes with overly aggressive setups. Every component, from the muffler to the polished-finish silver piping, is crafted to survive the harsh conditions that come with daily driving and off-road adventure alike.
Performance and Sound
At the heart of the system is the 2.50-inch Flow FX “straight-through” performance muffler, which mounts high in the frame rail just behind the factory catalytic converter. This straight-through design promotes efficient exhaust flow while producing a moderate, deep, and powerful tone that sounds great at idle and under throttle, yet stays comfortable on the highway. If you want your TJ to sound stronger without becoming obnoxious, the Flow FX series hits that balance.
Built for the Trail
The 2.50-inch mandrel-bent stainless steel tailpipe is tucked up high in the undercarriage, protecting it from being crushed when you traverse rocky terrain. Mandrel bends keep the internal diameter consistent through every curve, helping preserve flow. The system is finished off with a large 3.50-inch black ceramic coated stainless steel tip embossed with the Flowmaster logo, adding an aggressive, purposeful look at the rear of your Wrangler.
Easy At-Home Installation
This is a true direct-fit, cat-back system. It uses the factory hanger locations and includes installation instructions along with all the hardware necessary for a quick and easy installation you can complete in your own garage. There is no need for cutting or custom fabrication when you follow the included guidance, making this an approachable upgrade for weekend DIYers.
