Most aftermarket catback systems for the RS3 are designed to mimic the factory twin pipe setup making it easy to connect to the downpipe.  This was fine for factory or mildly tuned setups, however the split pipe system can not keep up with the flow demands of aggressively tuned engines and big turbo setups, causing power loss.  The IE catback center pipe is a massive 3.5" straight-through pipe that splits to dual 3" pipes out the back with the valves open.  This is enough flow to power even the largest turbo setups.

The built-in valve system is fully controlled by the factory drive select button just like stock without the need for finicky Bluetooth apps or cumbersome key fobs.  Simply select comfort to drive around your suburb like a civilized neighbor -or select dynamic to blow their ears out with that 5 cylinder roar!

IE engineers use 3D scanning tools to create a digital duplicate of the vehicle's under body.  This provides an incredibly high resolution environment to reverse engineer and rapid prototype a performance exhaust that not only takes advantage of every millimetre of available room, but also results in a perfect fit and easy installation.
