BMW released it ‘s latest accessory from the BMW Performance line today with the M3 Performance exhaust. With a weight reduction of 20 lbs (around 40%) over the standard unit the exhaust gives the M3 a bit more sinister of a note. One thing to note – BMW doesn ‘t promise any performance increases. Instead they ‘re only touting weight savings and exhaust note improvements. Is it worth the $4,374 plus installation? We ‘ll let you and M3 owners be the judge of that.

One thing that is worth the money are the free exhaust ringtones after the break.

We will have more first hand information on this and other M Performance accessories later in the week so stay tuned. In the mean time have a look and listen to the exhaust in action.

Official Release: BMW today announced a new M Performance exhaust system specifically designed as an accessory for the BMW M3 Coupe, Sedan and Convertible. With the racetrack and the street in mind, this new exhaust system is crafted from an extremely heat-resistant and lightweight chrome-nickel alloy called Inconel®. This flow optimized exhaust system reduces exhaust backpressure and allows the M3’s 414 horsepower V8 engine to produce an even more powerful sound.

Inconel’s unique qualities allowed engineers to reduce the thickness of the tubing from 1.5mm to 0.8mm. This resulted in a weight reduction of approximately 40%, or about 20 lbs. when compared to the stock exhaust system. Inconel has also proven to be very corrosion resistant and has been used at the highest level of Motorsports.

The M Performance Exhaust includes perforated inner pipes and polished titanium tips, which are laser engraved with the M logo. It represents the ultimate in technology and sportiness, accentuating the individual character of the BMW M3. The exhaust was developed using state-of-the art CAD and FEM technology ensuring optimum fit and OEM quality.

The new exhaust may be installed at any Authorized BMW Center at a price of $4,374 plus installation. M Performance parts are warranted for the New Vehicle Limited Warranty period when the installation occurs before the first delivery of a new vehicle. If the M Performance parts installation occurs after the first delivery, the accessory will be warranted for the balance of the New Vehicle Limited Warranty period or two years and unlimited mileage from the date of installation, whichever one is greater.
