Made in the USA O2 Sensor Bung and plug. This weld-in bung allows an O2 sensor to be screwed into your exhaust system. It's required for custom exhaust systems, and is also useful for air/fuel ratio measurements when dyno testing. A threaded plug is included to cap off when not in use. Bung and cap/plug are both 100% stainless steel. The bung and plug are also available separately (in case you don't need both). Simply choose your option below.

Install Tips
  • Locate bung as close to engine a possible, without exceeding the maximum operating temperature for the O2 sensor. The suggested location is just down-stream of the merge-collector on each bank of cylinders.
  • Sensors located after upstream exhaust system leaks or too close to exhaust outlets are susceptible to poor readings or influence of ambient air
  • O2 Sensors exposed to exhaust gasses with too high amount of un-burnt fuel can lead to misleading readings. A possible lean reading.
  • Locate sensor/bung 90deg to exhaust gas stream.
  • Locate sensor/bung in tube with a minimum of 10deg up angel to prevent liquid build up in sensor element.
  • Use stainless steel welding wire or rod when installing bung.
  • Do not have bung plug or a oxygen sensor installed when welding bung in place.
  • Welding can distort the bung so it is recommended you chase/tap the threads of the bung after welding.
  • When installing O2 sensor or plug, use an O2 sensor compatible high temperature resistant grease on the threads.
  • Use tightening torque suggested by O2 senor manufacturer.

The sound is mildly more aggressive than the stock exhaust with a slightly more throaty note. This exhaust will waken up the stock M235i personality with a better sound and improved flow. If you feel the stock exhaust is just TOO quiet this is a great option without going overboard. A unique high-tech look is provided by two either chrome-plated or Carbon fiber 80mm exhaust tips which are laser engraved with the ///M logo.

This exhaust system includes the rear muffler (18302228673). Please select exhaust tip options below. Chrome - (18302354364) Carbon Fiber (18302355889) . A BMW factory exhaust clamp is included to mount to the factory cat section.

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.
