aFe is proud to introduce the aFe Twisted Stee non-catalytic down-pipe for the 2012-2015 BMW 335i (F30) 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.
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.
