CTS Turbo MK2 TTRS/8P RS3 High Flow Downpipe

The CTS Turbo high flow downpipe is designed specifically for the 2.5-litre five-cylinder engine in the 8P RS3 and 8J TTRS MK2 models. This performance exhaust component replaces the factory catalytic converter section to significantly reduce exhaust back pressure, allowing spent gases to exit more efficiently. The improved flow characteristics support better turbo spool response and enable more aggressive tuning potential. Constructed from durable mandrel-bent materials with precision flanges, this downpipe maintains proper clearances within the tight engine bay while delivering measurable gains when paired with appropriate ECU calibration.
