With the racetrack and the street in mind, this new exhaust system is crafted from a heat-resistant and lightweight chrome-nickel alloy called Inconel.
The flow-optimized system reduces backpressure and allows the M3’s 414hp 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 lb compared to the stock system. Inconel has also proved to be corrosion resistant and is used at the highest level of motorsport.
The M Performance Exhaust includes perforated inner pipes and polished titanium tips, which are laser engraved with the M logo. 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 $4374 plus installation.
M Performance parts are warranted for the New Vehicle Limited Warranty period if it is installed before the delivery of a new vehicle. If the installation occurs after 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 is greater.
