Milltek Sport (Audi, RS3 Saloon/Sedan 400PS 8V MQB, OPF/GPF) Large-Bore Downpipe and De-Cat

Milltek Sport's large-bore downpipe for the Audi RS3 Saloon/Sedan 400PS (8V MQB), OPF/GPF Models replaces the factory downpipe with a genuinely larger-diameter, less restrictive design, constructed from T-304 stainless steel throughout for long-term durability. Reducing backpressure at this point in the exhaust system typically delivers one of the most noticeable power and response gains available on a turbocharged platform, particularly when paired with a supporting ECU tune.

This version replaces the factory catalytic converter with a straight-through de-cat pipe, delivering maximum flow and the greatest performance gain of any Milltek downpipe configuration for this platform. Intended primarily for track and off-road use, worth checking local emissions regulations before fitting to a road car.
