Description

The Redstar Exhaust downpipes are designed for the Audi B9 RS5 and F5 RS4 models equipped with the 2.9L TSFI Twin Turbo engine. These downpipes feature a large-bore design with optimized transitions, reducing the OEM 127mm turbo outlets to an 89mm main section and then to 76mm. This engineering aims to improve exhaust flow, leading to enhanced power delivery, sharper throttle response, and a more aggressive exhaust tone.
