RaceHouse Kia Stinger 3.3T Valved Cat-Back Exhaust

The RaceHouse Valved Cat-Back Exhaust for the Kia Stinger 3.3T is engineered to deliver controlled sound, improved exhaust flow, and long-term durability without sacrificing daily drivability.

Manufactured from premium T-304 stainless steel, the system features precision mandrel-bent tubing designed to improve exhaust flow over the factory setup. The result is sharper throttle response and a deeper, more defined exhaust tone.

With the valves closed, the exhaust remains composed and refined for street use. Open the valves, and the system delivers an aggressive, commanding tone that matches the Stinger’s performance potential.

Sound tuning was carefully balanced to provide presence under load while minimizing unwanted drone during cruising. This ensures the exhaust remains enjoyable in real-world driving, not just wide-open throttle.

Whether you want restraint or full volume, this system gives you the choice.

Silence or Send It.
