Flowmaster introduces our American Thunder axle-back exhaust system for the 2024 Ford Mustang GT with the 5.0-liter engine or the EcoBoost 2.3L engine and the standard factory non-valved exhaust system. This system uses the Super 44 series mufflers for an aggressive exhaust tone and increased performance. Maximum dyno gains of up to 8 hp and 6 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. Dual 4.00-inch polished stainless steel tips are used to add a custom look to this iconic vehicle. All the necessary hardware is included and factory mounting locations are used for an easy installation. Fits both coupes and convertibles. Backed by Flowmaster's Lifetime Limited Warranty.
