When crafting the ECS exhaust systems, their primary focus is on achieving the perfect balance of sound and comfort. ECS's understand the desire for a thrilling exhaust note without the annoyance of highway drone or interior vibrations. The exhaust for your 135 incorporates this balance, offering a strageic blend of sportiness and practicality. Drawing from their extensive experience, particularly with N55 cars like the E9x series, they have engineered an exhaust packed with innovative features, compatible with both factory and aftermarket downpipes. Experience the perfect blend of performance and everyday usability.

There is something about a cat-back exhaust that is just so good. Being able to unbolt and replace the entire visible exhaust gives you butterflies in your stomach. A fresh new exhaust and just knowing that things are about to get rowdy. This exhaust features twin 2.5" brushed pipes with flanges that bolt directly to your factory and aftermarket down-pipes. The dual 2.5" mid-pipes make their way toward the rear axle and converge into a single 3" exhaust section. The 3" exhaust section snakes through the rear section of the car making smooth dips and curves to make its way into a light-weight 3" turbo style muffler. Don't be fooled by the 135 muffler, the size is nothing but deceiving. The turbo-style muffler features an inner design that refines the exhaust note to perfection. An extraordinary mixture of both tone and volume. Paired with the 3" muffler is your choice of 3.5" exhaust tips that give your rear diffuser a sporty look that shouts performance.

Although both N54 and N55 share identical exhaust geometry, the N55 mid-pipes do not feature secondaries. Though the N55 cat-back is compatible with N54 downpipes this is not suggested. Supposedly this N55 catback sounds absolutely glorious on an N54, even with aftermarket downpipes.

The oxygen sensor is vital to the performance and drivability of your car. The engine computer relies on data from the sensor to make adjustments in engine efficiency and performance. 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. There is no lifespan on O2 sensors but there are several fault codes that indicate a failed sensor (O2 monitoring, cat efficiency, O2 heating circuit, O2 readiness, and others). The O2 sensor is heated and has a self-calibration feature so once you get the codes or feel performance has suffered, a new sensor is a good starting point to get you back to peak performance. Bosch's Oxygen sensors are high quality and will give you the longest and best performance for the price.

This is the OEM Bosch oxygen sensor for BMW's with the N52, N54, and N55 3.0L engines. This 490mm bank 2 oxygen sensor is mounted after the catalytic converter.
