Description

SYS 21-26 FORD BRONC

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.

Important Notice relating to US Domestic Market Trucks & Pickups

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.
