Milltek Filter-back Exhaust for Audi A3 2.0 TDI 170bhp 2WD Sportback DPF (2008-2012) – Sharper Sound, Filter Retained
This is Milltek's particulate filter-back system for the Audi A3 2.0 TDI 170bhp 2WD Sportback DPF. 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 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.
