Construction & Design
This exhaust system is crafted from premium stainless steel, offering superior resistance to rust and corrosion compared to standard materials. The mandrel-bent tubing maintains a consistent diameter throughout bends, reducing turbulence and backpressure to improve exhaust scavenging and overall efficiency.

Advanced CNC robotic manufacturing ensures each component meets exacting tolerances for a seamless fit and finish. Polished welded-on tips enhance visual appeal and resist discoloration and wear, maintaining a showroom-quality look over time.

Designed with dyno-proven performance in mind, this MagnaFlow exhaust system improves exhaust flow, contributing to enhanced throttle response and potential power gains. The signature MagnaFlow sound is characterized by a resonant, powerful tone that is assertive yet controlled. Exterior sound levels remain moderate to avoid unwanted attention, while interior sound is kept mild, allowing for an enjoyable driving experience without excessive cabin noise.
