Polo GTI AW mit OPF | Milltek Sport Abgasanlage & How to!

He didn't stay stock for long... Our Polo GTI got a Milltek Sport exhaust system with ECE approval! The system is street legal, affordable, and top-notch workmanship is a given with Milltek Sport! Despite the OPF (Otto Particulate Filter), the Polo now sounds almost like a much bigger car. Once the system is broken in (around 1000-1500 km), we'll post another video, as the sound will change.
