APR T304 Stainless Valved Catback Exhaust for 2019-2024 Porsche 911 (3.0L) - CBK0054

Fits 2019-2024 Porsche 911 Carrera, Carrera 4, Carrera 4S, and Carrera S (3.0L). This APR catback exhaust system provides a direct plug-and-play upgrade for both base and Porsche Sport Exhaust (PSE) equipped 992.1 models.

Engineered to optimize exhaust velocity for turbocharged engines, this system features dual-path routing with 3-inch valved paths and 2-inch non-valved paths. The valved sections utilize cast T304 stainless steel housings that integrate seamlessly with the factory ECU valve actuation, allowing for a civilized tone at cruise and a free-flowing, aggressive note at wide-open throttle. Constructed entirely from brushed T304 stainless steel, the system employs CNC mandrel-bent tubing and TIG welding for maximum durability and precision fitment.

Weight reduction is a primary benefit; at just 17 lbs, the APR system is 10 lbs lighter (37% reduction) than the factory Porsche Sport Exhaust. The design includes a drone-eliminating muffler and utilizes CNC-bent, laser-cut brackets that bolt to factory mounting points for a simple, two-clamp installation.
