Creating a true Motorsport exhaust system requires a delicate balance of flow and harmonics. Extensive engineering and testing has produced a truly unrestricted exhaust with an exhilarating symphony of engine sound without annoying rattles, drones, or reverb cabin noise. Your stereo system may be out of a job!
Engineered To Perform
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
Exotic Tip Design
Whats the point of a larger exhaust that looks stock? Truly stand out from the crowd with a set of unique stylized exhaust tips. These custom shaped over-sized tips fill up the factory exhaust cut outs and update it with a look that belongs under a modern super car.
Available in your choice of a brilliant polished finish or an optional satin black to match your black optics package.
The exhaust tips are fully adjustable up, down, and in/out. The final look of how they sit is up to you! Choose a flush install or a more aggressive look past the bumper.
Fits With IE Or Stock Downpipe
Note: The IE Y-Pipe Adapter Is Required For Stock Downpipe
The Integrated Engineering Audi 2.5 TFSI 8V 8S Y-Pipe Adapter Kit (RS3 & TTRS) is used to adapt your IE catback to a stock downpipe exhaust section. This high quality stainless steel cast adapter is a complete kit that will make installing our catback to your stock downpipe painless and easy!

*Retains dynamic, comfort, individual, and auto modes.
Open Exhaust Valves
With the exhaust valves in their open setting (dynamic mode) the exhaust flows from the main 3.5" pipe into dual 3" pipes and directly out the back unrestricted. This setting offers both the highest flow and loudest sound possible from your exhaust.
Closed Exhaust Valves
Cruising in comfort mode closes the dual exhaust valves forcing the exhaust to flow from the single 3.5" center pipe into the muffler and out twin 2.5" pipes. This keep the sporty exhaust note, but with a dramatically reduced stock-like noise level.
Precision Fit
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.
Superb Craftsmanship
Each IE catback is manufactured from the highest standard 304L stainless steel, mandrel bent, and TIG welded by hand all using precise fixtures and tooling. We take great pride in knowing your new exhaust is built to last a lifetime.
Technology Meets Art
Cutting edge engineering and craftsmanship have blended together at every step from design to manufacturing delivering the highest quality surface finish, fit and material brightness. The exhaust tips feature horizontal, vertical, and depth adjustments so you can perfect them exactly as you wish. Not only will your exhaust sound and perform amazing, it will look the part as well.
