aFe is proud to introduce the aFe Twisted Stee non-catalytic down-pipe for the 2012-2013 BMW F30 335i with the L6-3.0L (N55) engine. In testing this system resulted in a max gain of 13 horsepower and 27 lbs. x ft. of torque and outflowed the restricted OE catalytic converter by up to 190%. This high performance race pipe delivers pure, race-inspired raw power and also produces an aggressive and exciting exhaust sound during hard throttle. aFe also used a massive, light-weight 4" diameter 304 stainless steel tube and progressively tapers to increase exhaust velocity and usable torque.

100% TIG-Welded by certified craftsmen for race proven strength and durability. TIG-Welding provides the strongest welds reducing stress cracks.

Tapered Design:
A unique 4" Dia. 304 stainless steel taper design is used to increase exhaust velocity and increase usable torque. This means more aggressive throttle response and increased passing power.

Factory O2 Sensor Locations:
Factory mounting locations for all O2 sensors.

Hassle-Free Installation:
OE style brackets are included for a hassle-free installation. This unit also comes with a lifetime warranty.

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