aFe Twisted Steel 4" Downpipe w/ Cat - F2X | F3X N20 2.0L

Part# 48-36303-HC

This aFe Power Twisted Steel, Street Series utilizes a 400 CPSI converter for maximum exhaust flow for the popular 2012 to 2014 BMW 328i with the N20 turbo motor. In recent dyno testing, this race pipe produced 13hp and 29lbs. x ft. torque and out-flowed the factory downpipe by 287%. This system uses a 4" diameter tube and progressively tapers to increase exhaust velocity and usable torque. This high-performance race pipe is constructed out of lightweight, TIG-welded 4" stainless steel.

Note: Does not fit vehicle with N26 engine. The N26 engine is SULEV (super low emission) version of N20.

Note: This is a "Race Only" product used solely for competition. Its use is limited to closed-course and open-course racing that is formally sanctioned by a recognized racing organization. Any other use including recreational off-road use could be in violation of local, state, and federal laws. A check engine light will emit and aFe recommends using a programmer but it is not necessary.

    All aFe exhaust systems are engineered and manufactured in our Corona, California manufacturing facility.
