Balanced Performance Sound. The Dynomax Ultra Flo Welded Cat-Back Exhaust is designed to improve exhaust flow while delivering a refined, moderate exhaust tone. Featuring a straight-through muffler design, this system helps reduce backpressure for enhanced horsepower and throttle response. It is an ideal upgrade for drivers seeking performance gains without excessive noise.
Construction and Appearance. This cat-back exhaust system is constructed from durable stainless steel for long-term corrosion resistance. The 3.00-inch exhaust tubing promotes efficient airflow, while polished chrome exhaust tips add a clean, aggressive appearance at the rear of the vehicle. Welded construction ensures strength and durability under demanding driving conditions.
Installation. Installation is considered moderately difficult and may require additional time or professional assistance. Drilling is not required, as the system is designed to connect to the factory exhaust mounting points.
Application. This Dynomax Ultra Flo Welded Cat-Back Exhaust fits 2015 to 2017 Ford Mustang GT Fastback.
