Description
Overview
The Flowmaster Signature Series Axle-back Exhaust System Kit is engineered specifically for the 2021-2026 Ford Bronco equipped with the 2.3 or 2.7-Liter engine. Built to unlock a deeper, more purposeful voice from your Bronco, this axle-back exhaust system pairs a TIG welded 304 stainless steel Signature Series style muffler with 3.00-inch mandrel bent tubing to deliver an aggressive to moderate sound level and genuine performance gains. If you’ve been searching to shop for exhaust upgrades that combine tone, flow, and durability, this catback-style axle-back setup checks every box.
Performance & Sound
Flowmaster measured maximum dyno gains of 17 horsepower and 18 lb-ft of torque at the rear wheels, so this isn’t just about looks and sound. The 3.00-inch mandrel bent, brushed 304 stainless steel tubing is designed to maximize exhaust flow and long-term durability, while the Signature Series muffler produces the deep, aggressive-to-moderate tone Flowmaster is known for. Whether you want a commanding note on the trail or a refined growl on the street, this performance exhaust delivers character without excess.
Build Quality & Appearance
Every joint is TIG welded for a stronger, more precise weld that looks as good as the system sounds. The silver, brushed 304 stainless steel construction resists corrosion and stands up to the elements, and the dual 4.00-inch PVD coated black chrome tips add a custom, finished look to this iconic vehicle. It’s a car exhaust upgrade built to be seen as well as heard.
