BMW Exhaust Parts, Mufflers & Catalytic Converters for BMW 4 Series F33 (2014+)

The Akrapovic Evolution exhaust systems for the BMW F30 335i & F32 435 are the result of the perfect integration of expertise, the best technology, and the use of the finest materials. Made of austenitic stainless steel, these systems feature a newly developed layout with two central link pipes replacing the single stock pipe, a new muffler design, and carbon fiber tailpipes.

This Akrapovic Evolution exhaust improves upon the stock exhaust system of the BMW 335i in numerous areas. The first visible improvement is the additional power of 7.1 HP (at 5.850 rpm) and 10.7 Nm (at 3500 rpm). The range between 2.000 rpm and 3.000 rpm and at 3.500 rpm was particularly improved. A noticeable improvement can also be observed at high RPM where the Evolution gives more power. This sporty elegance makes this Bavarian machine stand out from the rest and offers the taste of a more powerful version, accentuated with the additional power gains and weight losses of the Evolution system. The dual-mode ECU-controlled valve exhaust from Akrapovic offers stock-level sound at normal cruising, and a joyful deep sporty note when driving the 335i more dynamically. The Evolution systems replace the stock exhaust from the catalytic converters back.

Because of size and dimensions of this exhaust, it can not be shipped via conventional carriers such as UPS or FedEx, and must be shipped via Truck Frieght shipping. Not for sale outside the US or Canada.

This Akrapovic Exhaust fits the following BMWs:
2012+ F30 BMW 335i 335i xDrive - Sedan
2013+ F32 BMW 435i 435i xDrive - Coupe

The oxygen sensor is part of your BMW's emissions control system and feeds data to BMW engine management computer. The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. The goal of the oxygen sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today.
