Performance & Sound
Flowmaster measured maximum dyno gains of up to 17 horsepower and 17 lb-ft of torque at the rear wheels with this performance exhaust. The Outlaw-style mufflers are tuned for an aggressive exhaust tone, giving your Mustang a deep, race-inspired voice that matches its attitude. Every component of this car exhaust is designed to maximize exhaust flow without sacrificing durability, making it a standout among catback and axle-back options for the S650 platform.
Construction & Design
This exhaust system uses 3.00-inch mandrel-bent 409 stainless steel tubing to maintain smooth, high-velocity flow through every bend. The Outlaw mufflers feature a center inlet and center outlet with a 3.00-inch outlet diameter and a compact 6.50-inch overall length. To finish the look, quad 4.00-inch polished stainless steel tips with an embossed logo add a custom, aggressive appearance to one of the most iconic cars on the road. The silver painted pipe and black muffler finish keep the system looking clean under the vehicle.
