aFe POWER Twisted Steel headers for the 2013-2016 Porsche Boxster S/2014-2016 Cayman S (981) with the H6-3.4L engine produced a max gain of +22 HP and +22 ft. lbs. of TQ. These headers are constructed of near equal length mandrel-bent 1-7/8 IN 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 400 CPSI, catalytic converters and includes all components for a hassle-free installation with no modifications necessary.
TIG-Welded:
100% TIG-Welded by certified craftsmen for race proven strength and durability. TIG-Welding provides the strongest welds reducing stress cracks.
Dual High Flow Catalytic Converters:
Semi-metallic 400 CPSI catalytic converters are used for maximum flow.
Retains Factory Sensors:
aFe has designed this system to retain all your factory sensors for a hassle free installation.
Mitered Collectors:
Mitered collectors not only extend the tube lengths and decrease turbulence, but provide optimal exhaust scavenging. The result is increased horsepower, torque and improved throttle response.
304 SS Construction:
These headers are constructed of durable CNC mandrel bent brushed 304 stainless steel tubing for maximum performance, corrosion resistance, strength and resistance to cracking.
