Product Description

Upgrade your BMW's performance with the Agency Power Stainless Steel Downpipes. AP-335i-171 fits 2007-2009 BMW E90/E91/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 N54 engine comes standard with a bulletproof motor while packing a punch with not one but two turbos. This engine makes the perfect platform for hardware and software upgrades and was used in the early model 135i's. Agency Power's exhaust systems are by far some of the best on the market, fabricated from 304 polished stainless steel. They connect to the headers with a 3" diameter opening and V band flange. They have an inside diameter of 2.6". The larger diameter design will improve exhaust flow, spooling the turbos ealier, reduce exhaust back-pressure and improve throttle response. These downpipes eliminate the catalytic converters so it is reccommended you get an ECU reflash to eliminate CEL's. Each 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 twin turbo N54 cars.
