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.
