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!

• Stock Sport Exhaust 96 Decibels - Dynamic Mode
• IE Catback 105 Decibels - Stock Downpipe
• Full IE Turbo Back 117 Decibels - IE Catback & Downpipe
• Y-Pipe adapter available for stock downpipe

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! This part is not required if you are installing Integrated Engineering Audi 2.5 TFSI 8V 8S Performance Downpipe (RS3 & TTRS).

Easy Sound Control

Open Exhaust Valves

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.
