Description
Overview
The Flowmaster Outlaw Axle-Back Exhaust System is engineered to unleash a bold, aggressive voice on the 2021-2026 Ford Bronco equipped with the 2.3-liter or 2.7-liter engine. Built around Flowmaster’s iconic Outlaw-series muffler, this system delivers the deep, race-inspired tone that made the Outlaw name legendary while adding real, measurable performance to one of the most capable off-road platforms on the road today.
On the dyno, this system produced maximum gains of 14 horsepower and 16 lb-ft of torque at the rear wheels, giving your Bronco added punch to go with its attitude. The performance comes from 3.00-inch mandrel-bent 409 stainless steel tubing, shaped to maximize exhaust flow while standing up to the abuse of trail duty, weather, and years of hard driving.
Key Benefits
The Outlaw-series muffler is the heart of the system, delivering the aggressive sound level enthusiasts want without sacrificing durability. The 36.00-inch black muffler features a center inlet and side outlet with a 3.00-inch outlet diameter, feeding into a dual tail pipe layout that transforms the rear profile of your Bronco.
Finishing the look are dual 4.00-inch black chrome tips with an embossed logo, adding a custom, purposeful appearance to this iconic vehicle. The silver painted pipe finish and blacked-out muffler complete a system that looks as serious as it sounds.

Installation & Fitment
This axle-back system is designed as a direct fit for the 2021-2026 Ford Bronco with the 2.3-liter or 2.7-liter engine. It uses factory mounting locations along with all-new included hangers and the necessary hardware, making installation straightforward for a bolt-on upgrade.
