Description DEVELOPMENT AND TESTING: The 997.1 Carrera incorporates the catalytic converters into the rear exhaust, which leaves focus on optimizing the flow of the factory flow paths. By smoothing the interface between the flange/primary tubes, using smooth-radius, large-diameter bends, and implementing a collector with equal inputs from each primary, we have created a smoother exhaust flow path from the factory 3.6L headers (which do not have a true 3-1 merge collector) and a greater volume for 3.8L S model engines. This will increase exhaust flow and optimize your Porsche exhaust system without any drawbacks to sound quality, emissions, or check engine lights. CONSTRUCTION: Our precision-engineered headers are meticulously fabricated from T304L stainless steel. Proven design elements including port-matched flanges, smooth-radius primary tubing, and collectors that optimize the exhaust flow all work in conjunction to maximize power gains. Every set is rigorously quality-checked prior to shipping. BOLT ON AND GO: Each set of headers is tested in a fixture to guarantee fitment and then foam packed to ensure they arrive in perfect condition. Thorough header installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts. LIFETIME WARRANTY: Enjoy your SOUL exhaust parts with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any issues or answer any questions that you may have.
