Product Description

Upgrade your BMW's performance with the Agency Power Stainless Steel Downpipe. AP-N55-171 fits 2010-2012 BMW E90/E92/E93 335i models and the E82 135i.

The BMW 335i is out of the question one of the best tuner cars on the market today. Its N55 engine comes standard with a bulletproof motor while packing a punch with a single twinscroll turbo. This engine makes the perfect platform for hardware and software upgrades and was used in the later model 135i's. Agency Power's exhaust systems are by far some of the best on the market, fabricated from 304 polished stainless steel. This downpipe has an inside diameter of 4" with 2.5" flanges. The larger diameter design will improve exhaust flow, spooling the turbo ealier, reduce exhaust back-pressure and  improve throttle response. This downpipe eliminates the catalytic converter so it is reccommended you get an ECU reflash to eliminate CEL's. The downpipe includes two oxygen sensor bungs so you can retain the factory inputs. This downpipe is a must have power upgrade for all 135i and 335i enthusiasts with the single turbo N55 cars.

Downpipe Features

  • 4" 304 Stainless Steel Construction with dual 2.5" Flanges.
  • Mandrel Bent and Tig Welded design for sturdy construction.
  • V-Band connection to midpipe allows universal catback fitment.
