What is the Fi Exhaust RS3 Sportback system, and how does it work?

What is the exhaust made from?

T304 stainless steel construction throughout, with an optional ceramic nano-coating available for added thermal protection.

The catback runs 76mm-diameter piping and weighs approximately 23.4 kg (about 52 lbs).

How loud is the Fi Exhaust RS3 Sportback system?

Fi Exhaust rates the system at approximately 100.2 dB with the valves open and 90.3 dB with the valves closed.

Are downpipes available, and will they increase horsepower?

Yes. Race Downpipes are offered in a standard version and a sensor-equipped version with a dummy oxygen sensor, and Sport Cats are available in 100-cell race and 200-cell sport options. Fi Exhaust reports an average horsepower increase of 5 to 10% with the complete system fitted, in comparison to Factory Equipment.

Can I control the valves remotely?

Yes. Valve operation works through the car's factory sport button or drive mode selector, or can be upgraded to the Fi Exhaust Pro Control System for app-connected remote control.

Description

Fi Exhaust Valvetronic Exhaust System for 8Y Audi RS3 Sportback (OPF)

Fi Exhaust RS3 Sportback system is a valvetronic exhaust designed as a direct bolt-on replacement for the 8Y Audi RS3 Sportback with OPF, built from high-grade T304 stainless steel for durability and a dynamic soundtrack. Fi Exhaust’s valvetronic technology controls airflow and sound volume while enhancing performance and torque; when run as a complete system with the valvetronic catback and ultra-high-flow downpipe, it typically increases horsepower by 5-10%. With the valves closed, exhaust gases route through the muffler for a low-profile, comfortable drive; fully open, the system delivers a bold, sporty exhaust note. Switching between street and race modes runs through the factory sport button, drive modes, or the optional Fi Pro remote control upgrade, depending on your configuration. Uniquely designed muffler internals, engineered specifically for this chassis, deliver the distinctive sound and performance this system is built for.

Valve

Fi Exhaust systems are all equipped with valvetronic technology, designed not only to regulate sound volume but also to enhance overall vehicle performance. Before this technology, achieving both high horsepower and torque simultaneously posed significant challenges in exhaust system design. Valvetronic technology resolves this conflict, enabling sports cars to deliver powerful torque at low RPMs while achieving greater horsepower at high RPMs.

Fi Exhaust Pro Control System

The Fi Exhaust Pro Control System includes an intelligent control box, a two-button remote, and a mobile app. The app prevents check engine lights, monitors valve status, and enables Auto Mode based on RPM, speed, or boost. The remote allows precise valve control, with a customizable aluminum or forged carbon design.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
