Product Description

The PLM Private Label Mfg. Helmholtz Resonated Axle-Back Exhaust for the Infiniti Q50 is engineered to enhance performance and sound while preserving the refined character expected from a luxury sport sedan. Designed as a direct bolt-on replacement for the factory axle-back section, this system delivers a deeper, more aggressive exhaust tone without unwanted drone.

Built from high-quality 16-gauge 304 stainless steel, this axle-back exhaust features precision mandrel-bent piping and professional hand TIG welding for long-term durability and a precise OEM-style fit. Integrated Helmholtz resonators are specifically tuned to cancel harsh frequencies, resulting in a clean, sporty exhaust note that remains comfortable for daily driving.

Finished with large 4.5-inch dual-layer adjustable exhaust tips, this system not only improves exhaust flow and sound but also adds a bold, performance-focused appearance to the rear of your Q50.
