Flowmaster American Thunder Axle-Back Exhaust System - 818121
Looking for the perfect balance between a mild tone while cruising and at idle, but aggressive tone under throttle all while having no drone? The American Thunder axle-back exhaust system is perfect for the daily driven 2021-2026 Ford Bronco with the 2.3 or 2.7-liter engine. This system uses a tuned 60 Series style muffler for an aggressive to moderate exhaust tone and increased performance. Maximum dyno gains of 19 hp and 19 lb-ft. were measured at the rear wheels. 3.00-inch mandrel bent 409 stainless steel tubing is used to maximize exhaust flow and durability. A polished 3.00-inch stainless steel tip is used to add a custom look to this iconic vehicle. All of the necessary hardware is included and factory mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.
