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.

NOTE: If installing to OEM down-pipe you will require the IE Y-Pipe Adaptor (sold separately)

Just perfect.
Style: 3 Tier Cart
This cart is beautiful, solidly built and accurately engineered. The gold color is soft and a bit pearlescent. This is very nice and the smoked glass is attractive. The assembly was easy although it took a minute to find the bolts, they are in the frame pieces and need to be removed. This was great because each screw was perfectly threaded. The entire thing was wrapped in bubble wrap and yards of strong tape. It took just as long to unwrap it as it took to build it. A few supports were bent, but were easily fixed with pliers. The finished cart moves smoothly on unobtrusive casters and the shelves don’t rattle because they’re supported by suction cups inserted into the frame. This is a substantial piece and will be very serviceable for entertaining.

Very Sturdy and attractive bar cart.
Style: Square Carts
I am very impressed with the quality of this bar cart. I purchased it for the appearance/styling of it. I looked at 20 - 30 bar carts and this one was the best fit to compliment my kitchen decor. I wasn't expecting the metal to be strong & sturdy, but it was. From the amazon photo, the metal frame looked lightweight and hollow. I also could not tell by the amazon photo if the gold matte finish would look cheap or elegant. I was very pleased with the finish. It was not the shiny brass type finish that I do not like. It was easy to assemble. A friendly F.Y.I. I spent a little bit of time looking for the assembly screws, expecting them to be in the bag with the wheels. They were screwed into the frame pieces which I think is a great idea when packing an item. It 's a good way of knowing that all the screws were sent and that they fit. I will note that because of the solidness of the frame, the delivered package might be a bit heavy for some. Also I found that using a drill on low speed with a star bit made the installation go very quickly.

Nice bar cart, Inaccurate shelf heights
Style: 3 Tier Cart, Style: 3 Tier Cart
Bar cart is nice, quite easy to put together. One of the most upsetting things is that the advertised/pictured 2nd shelf height is very wrong. It’s quoted at 18.1” tall but in reality it’s only 12.5”, the same as the bottom shelf - as confirmed in other reviewers photos. So half of my bottles have to go on the very top shelf. I reached out to the manufacturer about max shelf weight but they refused to give me an answer. I have about 30lbs+ on each shelf with the slightest bow in the center as there is only shelf support on the very ends.
