Do you happen to own a fourth generation BMW M3 Coupe,  Sedan or Convertible model, and if so, do you crave for a throatier  sound from its exhaust? If you answered yes to both questions and can  justify spending $4,374 plus labor for installation for a performance  exhaust system, then you may want to take a look the Bavarian firm's new  M Performance offering. 
 BMW  said the new exhaust system is crafted from an extremely heat-resistant  and lightweight chrome-nickel alloy called Inconel, which allowed the  firm's 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 pounds when compared to the M3's stock exhaust system. So  basically, you're getting a much lighter exhaust system with a more  powerful sound
