Description
Overview
The Flowmaster Force II Axle-back Exhaust System is engineered for the 2012-2018 Jeep Wrangler JK/JKU equipped with the 3.6L engine, delivering the performance-minded upgrade Jeep owners expect from Flowmaster. Designed for the driver who wants a moderate exterior tone paired with a mild interior sound, this Force II system strikes a refined balance—assertive enough to announce your Wrangler’s presence, yet livable on the daily commute and long trail runs.
At the heart of the system is a stainless steel 80 Series Crossflow muffler, tuned to produce a moderate sound level without the drone that plagues lesser aftermarket setups. From the muffler back, dual 2.50-inch mandrel-bent tailpipes route the exhaust cleanly, finishing in a pair of polished stainless steel tips with an embossed logo for a factory-plus appearance that complements the JK/JKU’s rugged styling.
Key Benefits
This is a true bolt-on, emissions-legal upgrade. Because the system utilizes the factory hanger locations and a flanged mount, installation is straightforward enough to complete in your own garage with basic tools. Every kit ships with the necessary parts, hardware, and installation instructions, so you have what you need to get your Wrangler back on the road quickly.
