Flowmaster's American Thunder Axle-Back Exhaust System gives your Bronco a tough sound. If you want better looks, an excellent sound, and better performance, all from a trusted name, this Flowmaster American Thunder exhaust is for you.
Better exhaust flow. The mandrel bent 3" exhaust tubing opens up the exhaust and provides smooth bends to reduce restriction. This improved exhaust flow gives you a bump in performance, worth up to +19hp and +19lb-ft of torque.
Aggressive sound. This axle-back delivers a moderate-aggressive exterior sound and louder interior noise so you can hear your exhaust, giving you a more exciting driving experience. American Thunder series exhausts are the 'original' Flowmaster sound. These chambered mufflers deliver a very aggressive sound in most cases.
