Description
Overview
The Flowmaster Flow FX Cat-back Exhaust System is engineered to upgrade the sound, style, and durability of your Jeep Wrangler TJ. Designed specifically for the 2000-2006 Jeep Wrangler TJ equipped with the 4.0L engine, this complete cat-back system replaces the restrictive factory piping from the catalytic converter back with a purpose-built, all stainless steel setup. It bolts directly to the factory flange and uses the factory hanger locations, making it a straightforward upgrade you can tackle in your own garage.
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 delivers a moderate, deep, and powerful exhaust note on the outside while keeping interior resonance to a minimum, so you get an aggressive tone without an overwhelming drone inside the cabin.
Built for the Trail
Off-road capability was clearly a priority in this design. 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 all stainless steel construction adds durability and longevity, standing up to the elements and the abuse of hard use, road salt, and moisture that quickly take a toll on lesser exhaust systems.
Style and Sound
The Flow FX system is finished off with a large 3.50-inch black ceramic coated stainless steel tip, embossed with the Flowmaster logo for a clean, purposeful appearance at the rear of your Jeep. The single tailpipe configuration keeps the look tidy while the moderate sound level strikes a balance between performance attitude and everyday drivability.
