High-performance axle-back system for aggressive sound and style.
The Flowmaster Exhaust System Kit is engineered for performance and durability, featuring a robust construction of 3-Inch mandrel-bent 409S stainless steel tubing. This system incorporates race-proven Outlaw mufflers, delivering an aggressive exterior sound while maintaining a noticeable interior sound level. The dual exhaust design exits through factory cutouts in the rear valance, complemented by quad 4-Inch polished stainless steel tips that enhance the vehicle's aesthetic appeal.
Designed for easy installation, this axle-back system utilizes factory hanger locations, allowing for a straightforward bolt-on process that can be completed at home in approximately one hour. The system retains the factory resonator mid-pipe, ensuring compatibility and performance. For those seeking additional sound and power, the optional Scavenger Series No Resonator X-Pipe is available.
Constructed from high-quality materials, the Flowmaster Exhaust System Kit offers improved long-term corrosion resistance and durability. The aggressive sound profile is further enhanced by the dyno-tuned design, ensuring maximum performance. This system is suitable for vehicles without active exhaust valves and includes all necessary hardware for installation.
