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
