Audi 8Y RS3 Sportback Fi Exhaust (Frequency Intelligent Exhaust) high-performance valvetronic exhaust system is direct replacement bolt on system manufactured out of a high-grade T304 stainless steel that offers an exhilarating soundtrack.

The Fi EXHAUST system is designed with a valvetronic technology to control airflow, sound volume and enhance the overall performance and torque. On average horsepower is expected to increase from 5-10% after installing a full catless system, which includes a valvetronic catback and ultra-high flow downpipe.

When valves are closed exhaust gasses are routed through the muffler resulting in a low-profile comfortable drive. However, when the valves are fully open an intense and sporty soundtrack is produced.

Depending on your car model and exhaust setup, switching exhaust valves between street and race modes may be achieved using a factory exhaust/sport button, drive modes, or by selecting the Fi Pro remote control upgrade. Please note that not all options are available for every model. Refer to the available section and contact our representative for confirmation.

The unique sound and performance for Audi 8Y RS3 Sportback is achieved through individually designed muffler internals that are fabricated to offer an ultimate driving experience.

Please note each part of the Fi EXHAUST system needs to be ordered separately.
Different exhaust parts are offered depending on the vehicle version.

Please note that the actual product may vary in appearance depending on the year of the car and area. The exhaust system is also subject to changes to the design over an extended time period. Product pictures are for illustration purposes only.

Nice, sturdy and easy to assemble.

Worked great for our small apartment. We needed something to fit over our heater baseboard and this worked! However, we had to swap the bottoms and top side rods to fit this way, meaning instead of using the 6” rods at the bottom we put them on top and used the 12” at bottom to clear over the baseboards. Easy to assemble and matched our other larger wall shelf perfectly.

Color: Rustic Brown and Black, Color: Rustic Brown and Black
We couldn’t add built ins because of our vents so went with theses instead and they were exactly what we needed! Very durable, sturdy, and a great height! Bought one first then decided we wanted another! They look great for decorations plus for our babies toys! Comes with everything you need, drywall screws and all. Would buy another if I need it in the future!

Looks Fantastic, but you HAVE to follow the setup directions!
Color: Rustic Brown and Black
BLUF: I bought this for my office to display photos, awards, and such and I am very happy with the purchase. Background: I moved into a new house and needed to organize my office. Like most people, I have a bunch of nicknacks, paperweights, and small gifts given over time. And like most people, I had no efficient nor aesthetically pleasing way to display all of the items. I didn't want a big solid bookcase, but more of a display case to show them all off. I bought this and am very happy with the results. I would suggest it to anyone, however it is not perfect. PROS: Enough shelves with enough space to hold all of the small items that I had. It is solid if installed correctly. Additionally, it is smaller and fits flush against the wall, giving the room organization and improving it, while not overburdening it and making the room feel crowded. CONS: The main issue is that the single bar going up through all of the shelves makes it very flimsy if you don't secure it to the wall. YOU MUST SECURE IT TO THE WALL PROPERLY!!! I cannot express that more. Once you do, it becomes a solid piece, but it will not function properly if you do not secure it at all 4 attachment points. Overall: I would buy this again!
