aFe 08-13 BMW 128i (E82/88) L6 3.0L Twisted Steel 304 Stainless Steel Long Tube Header w/ Cat

aFe POWER Twisted Steel Long Tube Headers are constructed of near equal length 1-1/2 IN 16-gauge 304 stainless steel tubing with thick 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. It uses dual, high flow, 300 CPSI metallic catalytic converters for maximum flow providing an astonishing low end torque improvement. All components are supplied 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. The ceramic 300 CPSI metallic catalyst is designed for maximum surface area and flow. aFe has designed this system to retain all your factory sensors for a hassle free installation. Also included are 6 O-ring header flange gaskets. 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. These headers are constructed of durable CNC mandrel bent brushed 304 stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking.
