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
2013+ F33 BMW 435i Convertible 435i xDrive Convertible- Convertible

A new oxygen sensor can improve driveability and lengthen engine life. Ultimately, you achieve a smoother running engine that is more fuel efficient. Feedback from the oxygen sensor provides closed-loop control of the injected quantity of fuel for optimum air-fuel mixture, enabling virtually complete combustion to take place. Contaminants in gas and certain atmospheric conditions can drastically shorten the life of any oxygen sensor, therefore they should be checked with every periodic maintenance and changed if necessary.

This is the OEM Bosch oxygen sensor for BMW's with the N20 and N26 motors. This sensor is mounted in the catalytic converter in the rear most position. OEM replacement for BMW # 11787589122.
