aFe POWER 2001-2002 BMW Z3M (E36) Twisted Steel Headers by aFe Power
aFe Powers new Race Only Twisted Steel Headers deliver an astounding 12hp and 16lbs. x ft. torque while outflowing the factory exhaust manifolds. The headers are constructed of near equal length 1.625 16-gauge 304 stainless steel tubing with 3/8 thick CNC machined flanges to ensure a leak free seal. To eliminate dead space that can cause turbulence and hinder flow that formed collectors are prone to produce, true merge collectors and optimized tube lengths are used for true pulse control technology improving flow and performance. 100% TIG-welded, the smooth curves and increased diameter of this header helps remove restriction and keeps exhaust gas flowing smoothly for improved performance and durability. All components are supplied 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.
Retain 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.
CNC Machined Flanges: Flanges are CNC machined not only to be visually appealing but for a precise fit and leak-free seal.
Brushed 304 SS Construction: These headers are constructed of durable CNC mandrel bent brushed 304 stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking.
aFe headers are engineered and manufactured in our Corona, California manufacturing facility.
