This is a factory BMW M Performance exhaust for the F87 M2 Competition. This is a factory BMW accessory so it fits great, looks and sounds phenomenal, and is of exceptional quality. The sound is mildly more aggressive than the stock exhaust with a slightly more throaty note. This exhaust will waken up the stock M2 Comp 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 four Carbon Fiber exhaust tips that are laser engraved with the ///M logo.
