CTS Turbo MK4 1.8T Downpipe High-Flow Cat

The CTS Turbo MK4 1.8T Downpipe with High-Flow Cat is designed specifically for 1999-2004 Volkswagen GTI and Jetta GLI models equipped with the 1.8-litre turbocharged engine. This replacement downpipe features a high-flow catalytic converter that significantly reduces exhaust backpressure compared to the restrictive factory unit. The improved flow characteristics enhance throttle response and allow turbocharged engines to spool more efficiently. CTS Turbo's construction ensures long-term durability under demanding conditions while maintaining emissions functionality for compliance-conscious workshops and enthusiasts.
