CTS Turbo Audi C7/C7.5 S6/S7/RS7 4.0T Cast Downpipe Race Set

CTS Turbo's cast downpipe race set replaces the factory catalytic converters on C7 and C7.5 generation Audi S6, S7 and RS7 models equipped with the twin-turbo 4.0-litre V8. Precision-cast construction delivers superior strength and heat resistance compared to fabricated alternatives. This catless configuration maximises exhaust gas flow from both turbochargers, reducing backpressure and improving throttle response. Designed as a direct bolt-in solution using OEM mounting points. Essential for tuned applications seeking unrestricted exhaust flow. Suits 2013-2018 model years across the C7 platform.
