APR Catback Exhaust for 992 3.0T & 3.7T

Our premium catback exhaust system for the Porsche 911 (992) is a full T304 stainless steel system with quad exits. It features dual 3" & 2" exhaust paths that creates an exhaust note that's sure to turn heads! The cross sectional area on the non-valved paths are 66% larger than stock, and the valved paths are 19% larger. Yet despite this, the system weighs 37% lighter than the upgrade Porsche Sport Exhaust (PSE)! The short valved paths let the system scream at wide open throttle with minimal backpressure and maximum exhaust velocity through the system, which is exactly what a turbocharged engine wants. And when cruising, the valves close, allowing the system to act civilized with enough growl to let you know it's there. Of course everything in the system is high quality. All tubing is brushed T304 stainless steel with mandrel bends and TIG welding throughout. The exhaust valves are cast and feature premium components. The mounting brackets are CNC-bent and CNC-laser cut for a precision fit. All this makes for a premium system that's simple to install, is larger than stock, weighs less than stock, and sounds amazing in every scenario.

SYSTEM OVERVIEW

The factory Porsche Sport Exhaust (PSE) is a large suitcase style muffler with valves and quad exit pipes. This system is fairly similar to the base system, but has a few upgrades, including larger factory piping. The PSE has 2.75” valved exhaust pipes, and 1.55” non-valved pipes and weighs in at 27 lbs. The APR system eliminates the large suitcase muffler and creates a short and simple path for non-valved exhaust path. In our testing, this routing gave the system the least amount of back pressure and highest exhaust velocity, compared to an x-pipe style setup. Lowering back pressure is ideal for power delivery and lowering exhaust temperature on turbocharged vehicles, and thus was a critical design criteria when developing the system. When the valves are closed under light use, the exhaust gasses are routed through a small muffler that eliminates drone and reduces sound volume. All piping was upgraded in size. The cross sectional area of the non-valved path was increased 66% increasing diameter from 1.55” stock, to 2”. The valved path was increased 19% by increasing diameter from 2.75” to 3”. Despite being larger, the APR system weights 37% lighter by reducing the system 10 LBS by reducing the system from 27 LBS stock, to 17 LBS.

EXHAUST VALVES

Our system features two valves that allow controlling sound volume in various scenarios via the factory valve actuators. In doing so, the system goes from tame to aggressive instantly! Unlike pneumatic systems, and other common valves found on the market today, our system maintains identical Oem operation all the way down to the factory valve actuation angles. We cast the valve housings out of T304 stainless-steel. Internally the system uses CNC-machined T303 components and bronze brushings, which have stood up to our extreme torture testing. All necessary hardware is welded into place and is designed to combat heat and vibration for years to come.
