aFe 2008 - 2013 BMW 128i (E82/88) / 2006 325i/330i / 2007 - 2013 328i L6 3.0L Twisted Steel 304 Stainless Steel Long Tube Header w/ Cat

48-36307-1

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.

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:
The ceramic 300 CPSI metallic catalyst is designed for maximum surface area and flow.

Retains Factory Sensors:
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:
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 and strength eliminating cracking.

Emissions Disclaimer:
This product is EPA compliant, not for sale or use on vehicles certified for the state of California. Consult your state or local authority for any additional clarification. Replacement of catalytic converters (if equipped) is allowed only under the following conditions: 1) if the vehicle is missing a converter; 2) if a state or local inspection program has determined the existing converter has been lead-poisoned or damaged or otherwise needs replacement; or 3) if the vehicle is more than five (5) years old or has more than 50,000 miles and a legitimate need for replacement has been established and documented. This product only fits those vehicles as listed in the application table.

aFe headers are engineered and manufactured in our Corona, California manufacturing facility.
