BMW will now offer an after-market upgrade for the M3 range - M Performance exhaust system.

The new sport exhaust system is made f a new heat-resistant material called Inconel, a chrome-nickel alloy. It reduces back-pressure inside the exhaust resulting in a new sound (check the video). Furthermore, the whole system is lighter than the original with 9 kg (20 lbs).

The aftermarket exhaust can be recognized by the laser-engraved M logo on those tips.

The price is $4 374 (€3 192), which is kind of expensive for just a sound, which is gorgeous already. The price excludes the installation.

However, you can still download the exhaust sound as a ringtone from www.bmwusa.com.

Enjoy the video!
