Milltek GPF Back Exhaust System for the Audi 8Y RS3 Saloon transforms the sound of the RS3's 2.5 5-cylinder TFSI engine whilst retaining the factory OPF filters to keep emissions 100% compliant. The system runs from the OPF to the tips, with the choice of a resonated or non-resonated section depending on your personal preference. The resonated system is the quieter option, whilst the non-resonated pipe is straight with no restriction until the backbox. If you're looking for a full OPF delete with a sports cat or decat, please click here to see your options.
No matter which system you opt for, rest assured your new Milltek system will make a noticeable difference with power gains, improved noise and a sizeable weight saving.
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.
