aFe Power's introduces the Twisted Steel header for the 2013-2016 Scion FR-S/Subaru BRZ with the H4-2.0L engine. In testing, these headers produced a max gain of +10 horsepower and +13 ft. lbs. of torque verified by our in house dyno. aFe spent countless hours of R&D to develop the perfect balance of pure, race-inspired performance and sound with zero drone. The headers are constructed of near equal length mandrel-bent 1-5/8" 16-gauge, 304 stainless steel tubing and uses thick flanges for added strength and to ensure a leak free seal. The smooth curves and increased diameter of this header helps remove restriction and keeps exhaust gas flowing smoothly for improved performance and response. To eliminate dead space that can cause turbulence and hinder flow a 4-to-1 formed collector and optimized tube lengths are used to help increase exhaust velocity improving flow, torque and throttle response. Incorporated in the header is a 200 CPSI, 48-state legal catalytic converter and includes all components for a hassle-free installation with no modifications necessary.
100% TIG-Welded by certified craftsmen for race proven strength and durability. TIG-Welding provides the strongest welds reducing stress cracks.
High Flow Catalytic Converter:
A 200 CPSI catalytic converter is used for maximum flow.
Retains Factory Sensors:
aFe has designed this system to retain all your factory sensors for a hassle free installation.
The 4-to-1 formed collector is used as an efficient way to collect header primary tubes together.
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
aFe headers are engineered and manufactured in our Corona, California manufacturing facility.
