Milltek Filter-back Exhaust for Audi RSQ3 2.5T Sportback & SUV (OPF/GPF Equipped Models Only) (2020 onwards) – Sharper Sound, Filter Retained
This is Milltek's particulate filter-back system for the Audi RSQ3 2.5T Sportback & SUV (OPF/GPF Equipped Models Only). It replaces everything downstream of the factory diesel or petrol particulate filter with wider-bore pipework and re-tuned silencers, cutting back pressure and sharpening the exhaust note. The filter itself is left exactly where the manufacturer fitted it, so emissions equipment is unaffected. It's offered in EC approved or race versions, so you can pick the setup that suits how the car's used.
It's the right choice if you want a sportier sound and a genuine, if modest, flow improvement on a filter-equipped car, without going anywhere near the parts of the system that keep it emissions-compliant.
