Flowmaster's® Signature Series Axle-back exhaust system for the 2021-2025 Ford Bronco with the 2.3 or 2.7-Liter engine. This system uses a TIG welded 304 stainless steel Signature Series style muffler for a deep exhaust tone with an aggressive to moderate sound level and increased performance. Maximum dyno gains of 17 hp and 18 lb-ft. were measured at the rear wheels. The system uses 3.00-inch mandrel bent brushed 304 stainless steel tubing to maximize exhaust flow and durability. This premium exhaust system is TIG welded for a stronger, more precise weld that looks as good as this system sounds. Dual 4.00-inch PVD coated black chrome tips are 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.
