IE CATBACK & 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.
CLASSY & UNIQUE
- 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 POLISHED OR SATIN BLACK FINISH
- Available in your choice of a brilliant polished finish or an optional satin black to match your black optics package.
- FIT TO YOUR TASTE
- The exhaust tips are fully adjustable up, down, in 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.

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.

Pieces chewed off
Color: white & green
My Aussiedoodle loves it. I throw it down the hallway, it bounces crazy, and he chases it. The only complaint is that he can't chew much of the ball part. So now I have to have it put away and brought out for special playtime.

Heavy chewer approved.
Style: Ball, Size: Medium (Pack of 1)
My pomsky will destroy a toy in minutes. Ropes, and the "indestructible" nylon type stuffs are no match for my furry shark. This ball has stood up to him like David. He loves the crunch and it is so much more tolerable than a squeaker. These will be a staple in his toy box - Chuckit toys are really the most durable dog toys I have found in three years.

Dogs love them
Style: Ball, Size: Medium (Pack of 2)
Our dogs love these. What’s great is that you can add more plastic (like from water bottles) if the plastic starts to fall out from the center. If you have a chewer, though, these won’t last you long. Our shepherd mix loves these and then starts to pull the rubber apart the more she plays with it. Our other dogs treat it normally, though, and those ones last forever. They also get some decent height when bounced, and they make a unique whistling noise when thrown.
