The MagnaFlow Competition Series Cat-Back Performance Exhaust System #19406 delivers an aggressive, attention-grabbing edge to the deep, resonant exhaust tone MagnaFlow is famous for, perfectly complementing the 2018–2023 Kia Stinger 3.3L. Designed with competition-focused performance in mind, this exhaust system enhances both sound and power with dyno-proven results.
The system features fast-flowing 2.5-inch mandrel-bent main piping that routes through six straight-through and tuned chamber mufflers, before terminating in a sporty quad split rear exit. The result is improved exhaust flow, increased horsepower and torque, and a bold exhaust note that matches the Stinger’s aggressive styling.
Exhaust kit #19406 utilizes a cat-back layout, replacing the factory exhaust components from near the catalytic converter on back. It is tuned to deliver aggressive exterior sound levels with moderate interior sound, fitting its competition-oriented design.
Developed using extensive 3D scanning, this system offers a direct-fit, bolt-on installation that makes installation quick and hassle-free. Constructed from 100% durable, corrosion-resistant stainless steel and manufactured using advanced CNC robotic precision techniques, this exhaust system is backed by MagnaFlow’s limited lifetime warranty.
