APR Catback Exhaust System for Porsche 911 (992) 3.0T | CBK0054

The APR Catback Exhaust System (CBK0054) is the ultimate lightweight performance exhaust for the Porsche 911 (992) 3.0T. Engineered to outperform both the base and Porsche Sport Exhaust (PSE) options, this full T304 stainless steel system utilizes dual 3-inch and 2-inch paths to optimize exhaust velocity. By significantly increasing cross-sectional area—up to 66% on the non-valved paths—this system minimizes backpressure, allowing the twin-turbocharged flat-six to breathe more freely while delivering a visceral, motorsport-inspired soundtrack.

One of the most impressive feats of the CBK0054 is its weight. Weighing in at only 17 lbs, it is 37% lighter than the factory PSE system (27 lbs), shedding 10 lbs from the very rear of the vehicle to improve weight distribution. The system features high-quality cast valve housings that integrate perfectly with the factory ECU actuators, allowing the car to maintain a civilized growl during cruises while screaming at wide-open throttle when the short, high-velocity valved paths open.

Features:

• Significant Weight Savings: 37% lighter than factory PSE, reducing rear-end weight by 10 lbs.
• Increased Flow: Cross-sectional area is 19% larger on valved paths and 66% larger on non-valved paths compared to OEM.
• Active Valve Technology: Cast T304 stainless steel valve housings retain factory ECU actuation for variable sound levels.
• Premium Construction: CNC-mandrel bent T304 stainless steel with argon back-purged TIG welding.
• Drone-Free Design: Includes a drone-eliminating muffler to ensure a pleasant cabin experience during highway cruising.
• Precision Fitment: Features CNC-bent and laser-cut bracketry for a perfect, rattle-free installation.
• Simple Install: A single-piece design that requires only two clamps and two mounting features.
