If you’ve ever driven an RS4 B7, you know how special it feels. Now imagine enhancing that experience with more sound and sharper feedback. That’s exactly what the Milltek Audi RS4 B7 Exhaust promises, and it absolutely delivers.
It’s not just about louder noise. It’s about unlocking the true character of the 4.2-litre V8 while still keeping the car refined when needed.
A Soundtrack Worth Replaying
Milltek revisited the RS4 B7 to create a Version 2 exhaust system that builds on the cult status of the original. At the heart of this update is modern silencer technology and an active centre H-pipe with vacuum valves.
The result? A noticeable shift in sound personality depending on Sport mode status.
What Happens When You Hit Sport Mode?
With Sport mode off, the active H-pipe opens and allows exhaust gasses to mix, while rear valves close for a smoother, dampened tone.
Turn Sport mode on, and it’s a different beast. The H-pipe shuts, each side breathes independently, rear valves open, and the gasses bypass silencers. That’s where the aggressive V8 note comes to life.
This dynamic exhaust setup mirrors what Audi offers on its latest RS models, but with a twist tailored for a modern classic.
Engineered for Performance and Longevity
Milltek’s exhaust is made from high-grade T304L stainless steel. Like always, it comes with a lifetime warranty for the original buyer.
From left and right resonators to valved outlets and brackets, the system arrives ready to install. Owners won’t need to worry about fitment or compatibility, Milltek has that covered.
Even better, the Sport mode button on the steering wheel still controls the valve system just like factory setup. Only now, it’s paired with even more satisfying acoustics.
Design That Complements the RS4’s Character
This isn’t just about what you hear, it’s also about what you see. The system finishes in oval OE-style tips, available in four distinct looks: Polished Stainless, Cerakote Black, Brushed Titanium, and Burnt Titanium.
Each option offers a different vibe, from subtle factory appearance to track-ready aggression. Whatever you pick, it’ll elevate the rear profile without shouting for attention.
Still Need EC Approval?
Milltek hasn’t forgotten about European drivers who require EC-approved systems. The original V1 exhaust remains available, delivering enhanced tone while staying within strict noise regulations.
It’s the best of both worlds: choice and compliance.
Summary
The Milltek Audi RS4 B7 Exhaust takes a beloved modern classic and injects it with new life. Whether you’re in the mood for quiet confidence or full-throttle fury, this system lets you choose with a press of a button. Built with precision, backed by warranty, and styled to match the RS4’s legacy, this is a must-have upgrade for any true enthusiast.
