APR 21-25 Porsche 911 Turbo/Turbo S (992.1) 3.7T Catback Exhaust System

Our premium cat-back exhaust system for the 992.1 Porsche Turbo & Turbo S (911) 3.7L 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.

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.
