AFE Twisted Steel Downpipes

Product images may differ from actual product appearance.

Cat-delete downpipes from aFe Power eliminate the catalytic converter for maximum exhaust flow on the popular 2012 BMW 328i with the N20 turbo engine. In dyno testing, these performance race pipes produced 13 HP and 29 ft/lbs torque, outflowing the factory downpipe by 287%. Made of lightweight TIG-welded stainless steel, pipes feature 4" tubing that progressively tapers to increase exhaust velocity and usable torque.

  • Lightweight Stainless Steel Construction
  • Factory O2 Sensor Locations
  • Tapered Design Outflows Stock Pipe Nearly 300%
  • Hassle-Free Installation

    Note: Not for vehicles with the N26 engine, which is the SULEV (super low emission) version of the N20
