Milltek Audi RS3 8Y Large Bore Downpipe, Decat & GPF Bypass replaces the factory components to create a much more free-flowing and less restrictive exhaust system. This system eliminates the factory catalytic converters, as well as the OPF filters to open up the exhaust for improved noise and increased tuning potential.

Milltek Sport exhausts are produced using high-quality type 304 aircraft-grade stainless steel. This material is anti-magnetic (other manufacturers' stainless steel may not be) and is less susceptible to discolouration. This quality of stainless steel is used on all pipework and the total construction of the silencer. Mandrel bending ensures full flow bends for better gas flow and Milltek Sport exhaust systems are increased in bore to ensure ultimate performance without the loss of mid-range torque. All Milltek Sport exhausts are designed, developed, and manufactured in-house in the UK.

*Please note: As this removes OEM emission-reducing software, this exhaust upgrade is not EC approved and therefore not legal for road use.

This setup will require stage 2 tuning software.
