IE's catback exhaust is a complete performance upgrade that delivers an aggressive note from your iconic five-cylinder engine while freeing the exhaust flow for the highest power levels from any turbo setup. Let your 2.5L beast roar with the ultimate Audi RS3 exhaust system. 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.

PRECISION FIT

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.

SUPERB CRAFTSMANSHIP

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.

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.

Very well built.
Well build. Very solid for the price. I used #1 AWG cable. I don't like the pinch bolt connection. It tries to drill through the cable, and spreads the strands. Only about 2/3rds are pinched under the knurled bolt tip. I'll keep an eye on it, and if the connection heats up, I'll pull apart, straighten the strands, and tin the ends with solder so they don't crush much. See how that works. A concave, half circle piece under the pinch bolt would be better IMO. That would keep strands together as they crushed down.

Solid choice for fuse holder
Size: 300A Fuse Holder
It’s awesome, solid connections for running 0 gauge wire. No issues after using for months! Might upgrade to using 0 gauge wire ferrules to use with this but for now everything is working well.
