Milltek Large-bore Downpipes with 200 Cell HJS High Flow Cats - Audi RS4/RS5 B9 non GPF Porsche we extract 155–165bhp and 180–190ft/lb

we extract 155–165bhp and 180–190ft/lb from all variants

This intake system has been developed to offer the highest possible flow rate whilst maintaining the lowest intake temperatures possible

free flowing pipe that joins the turbo inlet to the intake with a substantial increase in overall internal volume to reduce restriction and improve flow

We designed the shape with a continuous curvature and maximised the internal volume without affecting the airflow negatively

maintaining a 53mm minimum as it reaches the new cast aluminium throttle body elbow

Milltek Large-bore Downpipes with 200 Cell HJS High Flow Cats - Audi RS4/RS5 B9 non GPF Porsche we extract 155–165bhp and 180–190ft/lbEvery Milltek system is designed, developed and hand finished here in the UK by time served craftsmen, each one produced in aerospace grade type 304, non magnetic stainless steel. This superior material is less susceptible to discolouration, lasts almost indefinitely and is used throughout the entire construction of our pipework, silencers and associated hardware. Mandrel bending ensures constant radius bends for optimised gasflow, and bore diameters
