aFe Power's introduces the Elite Twisted Steel headers for the 2013-2014 Porsche Cayman S/Boxster S (981) with the H6-3.4L engine. In testing, the headers produced a max gain of +22 horsepower and +22 ft. lbs. of torque verified by our in house dyno. These headers are constructed of near equal length mandrel-bent 1-7/8" 16-gauge, 304 stainless steel tubing with thick flanges to ensure a leak free seal. The smooth curves and increased diameter of the headers helps remove restriction and keeps exhaust gas flowing smoothly for improved performance and durability. To eliminate dead space that can cause turbulence and hinder flow 3-to-1 mitered collectors and optimized tube lengths are used for true pulse control technology improving flow and performance. These headers use 200 CPSI, 48-state legal catalytic converters to prevent check engine lights and includes all components for a hassle-free installation with no modifications necessary.
