An updated exhaust with Active H-pipe has been launched by Milltek for the Audi RS4 B7 as part of its range for modern classics.
The stainless steel system has an Active H-pipe with vacuum-operated valve to allow for a Sport mode with a noticeable increase in exhaust noise. With the valve closed, the exhaust is more subtle for normal driving.
Also included with the system for the 414bhp 4.2-litre V8-powered Audi are left and right centre resonators, silencers and valved outlets, plus rear brackets. There are also oval OE-style trims that come in a choice of four finishes – Polished Stainless, Cerakote Black Stainless, Brushed Titanium, Burnt Titanium.
For RS4 owners in Europe who need an EC-Approved replacement system, the original (V1) system will still be available offering an enhanced tone within the noise limits set by the official approval standards
Technical Operations Manager at Milltek, Kev Hall, said: ‘Everyone has a soft spot for the RS4 B7 as it was one of the first Audis that felt so dynamically competent with a V8 engine that desperately needed to be heard, which is why it is a perfect car for a Milltek exhaust system to enhance its sound and performance delivery.
‘I’d describe it as a Jekyll and Hyde exhaust: with Sport mode off it is silky smooth and subtle, then with Sport mode on everything opens up and you really get the full sound of the exhaust as the rear valves open and the active centre closes, and vice versa with it off. It’s very similar tech to what we offer on the latest factory Audi RS models.’
