Unlock more performance and a dramatically more aggressive exhaust character from your Porsche 911 GT2 RS with the STRATEC™ Performance Exhaust Manifold Downpipes, engineered for the 3.8L twin-turbo flat-six platform.

Designed to reduce restriction immediately after the turbochargers, these high-flow downpipes improve exhaust-gas evacuation, reduce backpressure, and support increased horsepower and torque potential. Whether you choose the more street-oriented 200-cell high-flow catted version or the maximum-flow catless configuration, STRATEC™ delivers a direct-fit performance upgrade designed for serious GT2 RS builds.

Constructed from premium T304 stainless steel, each set features precision CNC-machined flanges, mandrel-bent tubing, and expert TIG welding for exceptional durability, heat resistance, and fitment.
