Audi F3 RS Q3 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 F3 RSQ3 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.

The History Teacher I Always Wished For
Format: Hardcover
With his trademark wit and his eye for those wonderfully absurd details that most historians tend to overlook, Metaxas drew me deeply into the story. I found myself laughing out loud one moment and profoundly moved the next. The tiny anecdotes and humorous asides were not distractions at all — they were precisely what made these towering figures suddenly feel human and unforgettable. Eric makes these historical figures flesh-and-blood again. He brings both heroes and villains vividly to life in a way that makes the drama of America’s birth feel immediate, thrilling, and deeply personal. In short, Eric Metaxas is the history teacher I always wished I had. At 600 pages, this book reads with the ease and momentum of a paperback novel, yet carries extraordinary depth and scholarship. In the end, I came away with a renewed love for American history and a deeper gratitude for the souls who made this great country possible.

A fun, inspiring, thought-provoking read.
Format: Kindle
A witty, learned page-turner, replete with wacky anecdotes but suffused by wisdom and patriotic love. Metaxas shows how the biblical view of the human person made America possible, and weaves throughout the story pieces of evidence that Providence actively aided the pious patriots against their cynical, post-Christian enemies in Britain. I devoured this book in 72 hours, and now I want to go back and read it again.

Is America the Greatest Nation in the History of the World? Yes. And let Metaxas remind you.
Format: Hardcover, Format: Hardcover
EXCELLENT! Just the book I wanted to prepare for the 250th. Less textbook, more like a long chat with a friend. A great refresher on the important events of the birth of our nation and deep appreciation for some the men and women who don’t always get attention. It is so incredible how many events had to come together for our nation to come together as the GREATEST Nation in the History of the World!
