The combination of N52 and muffler delete surpasses all sound expectations from a small 1 series! Impressive direct-fit solution. With this new muffler/res delete you can completely transform the sound and driving experience of your 128. A simple installation that can be completed with hand tools gives you the ability to take your car to the next level at home in your garage! What sounds better than an in-line six-cylinder paired with a race-inspired exhaust setup, the answer is nothing. You have a nimble chassis fitted with an engine that provides more than enough power for spirited street driving or even taking to the track, if the exhaust is still factory you do not know what you are missing out on.

The ECS N52 Muffler & Resonator Delete removes the heavy, restrictive factory muffler and replaces it with a lighter weight, high flow, T304 stainless steel 3.0" exhaust tubing. This exhaust adds a louder exhaust note in a simple, cost-effective way without replacing the entire exhaust system and is fully compatible with the OEM rear valance. This upgrade creates a noticeable increase in exhaust sound, without adding significant drone at cruising speeds. As an added bonus, the ECS muffler delete shaves off about 16 lbs, weighing in at only 22 lbs. OEM units out of the 128 weigh in at around 38lb, a difference you will fully notice when upgrading your exhaust.

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. This 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.
