High Flow Catted 200 Cell Downpipes for Porsche 911 997.1 Turbo 3.6T

Unleash the true performance of your Porsche 911 997.1 Turbo with the STRATEC High-Flow 200 Cell Downpipes, engineered to maximize exhaust flow and turbo efficiency.

Designed as a direct upgrade over restrictive factory components, these downpipes feature high-flow 200 cell catalytic converters that significantly reduce backpressure while maintaining improved emissions flow characteristics.
