Flowmaster 817942 2.5" American Thunder Axle Back System for 07-18 Jeep Wrangler JK

The American Thunder Axel Back System from Flowmaster gives your Wrangler JK the ultimate in performance on the road as well as the trail. This axle back system replaces your factory transverse muffler with a high tucked tailpipe giving you the clearance you need for your off road adventures while also adding horsepower, torque & thundering sound. The mandrel bent 409 stainless steel design increases airflow & prevents corrosion helping it withstand harsh outdoor enviroments. An aftermarket bumper is recommended for this axle back system because of how high the tailpipe is tucked.
