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.
Fits Porsche 911 (991.1 & 991.2) GT3, GT3 RS and 911 R (2014–2019) models.
Direct replacement for the factory headers; maintains bolt-on fitment.
Intended for vehicles with the original rear exhaust system; compatibility may vary with aftermarket systems.
