Creating a proper Motorsport exhaust system requires a delicate balance of flow and harmonics. Extensive engineering and testing have produced an unrestricted exhaust with an exhilarating symphony of engine sound without annoying rattles, drones, or reverb cabin noise.

TECHNOLOGY MEETS ART
Cutting-edge engineering and craftsmanship have blended from design to manufacturing, delivering the highest quality surface finish, fit and material brightness. The exhaust tips feature horizontal, vertical, and depth adjustments so that you can perfect them precisely to your liking. Not only will your exhaust sound and perform amazing, but it will also look the part.
ENGINEERED TO PERFORM
Most aftermarket catback systems for the RS3 mimic the factory twin-pipe setup making it easy to connect to the downpipe. This approach works fine for stock to mildly tuned engines but struggles to keep up with the demands of aggressive calibrations and big turbo setups. The IE catback center pipe is a massive 3.5" straight-through pipe that splits into dual 3" pipes out the back with the valves open. This design provides the flow required to power even the largest power goals.
RS STYLE TIPS
What is the point of a larger exhaust that looks stock? Stand out from the crowd with our new updated RS-style oval black optics exhaust tips. These oversized tips fill the factory exhaust cutouts for that high-end supercar look.
EASY SOUND CONTROL
The built-in valve system retains the factory drive select button functionality for an easy same as the stock control. Select comfort to drive around your suburb like a civilized neighbor -or select dynamic to blow their ears out with that 5-cylinder roar!
*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 central 3.5" pipe into dual 3" pipes and directly out the back unrestricted. This setting offers 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 of twin 2.5" pipes. This keeps the sporty exhaust note but dramatically reduces stock-like noise.
IE engineers use 3D scanning tools to duplicate the vehicle's underbody digitally. This provides an incredibly high-resolution environment to reverse engineer and rapidly prototype a performance exhaust that takes advantage of every millimeter of the available room and results in a perfect fit and easy installation.
Each IE catback is manufactured from the highest standard 304L stainless steel, mandrel bent, and TIG welded by hand, using precise fixtures and tooling. We take great pride in knowing your new exhaust is built to last a lifetime.
