CTS Turbo MK1 VW Tiguan and 8U Audi Q3 1.8T/2.0T High-Flow Cat Downpipe (2009-2017)

The CTS Turbo high-flow catalytic downpipe replaces the restrictive factory unit on MK1 VW Tiguan and 8U Audi Q3 1.8T and 2.0T models from 2009 to 2017. Engineered to reduce exhaust backpressure while maintaining emissions compliance, this downpipe allows your turbocharger to spool more efficiently and expel gases with less resistance. Precision mandrel-bent construction ensures smooth flow characteristics throughout the exhaust path. The integrated high-flow catalytic converter meets Australian Design Rule requirements while delivering measurably improved throttle response and reduced turbo lag across the rev range.
