Description
This performance header system is built specifically for your Porsche 991 GT3, GT3 RS or 911 R—replacing the factory restrictive manifold with long-tube runners, a billet CNC merge collector and high-flow studio-grade construction. You’ll experience improved throttle response, a more aggressive tone and greater airflow capacity under heavy load—all while retaining a track-ready build quality.
