VIDEO: Chris Bangle Butts Heads with Jason Castriota at SAAB's Geneva Motor Show Stand

You might think watching two world-renowned designers talking cars would be entertaining . . . and you'd be right on the money. Rising star and Saab's current hot shot design director Jason Castriota penned the PhoeniX concept. Chris Bangle, known for turning BMW on its head with his flame surfaces and unique rear ends, was hanging around Geneva and decided to chat with Castriota about his "aero" style.

Check out the video below for a minute and a half of a little (friendly?) banter between two polarizing designers as they discuss what makes the PhoeniX a Saab.

BMW Releases Performance Exhaust System for Latest M3 Models [with Video]

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

The M Performance Exhaust also comes with perforated inner pipes and polished titanium tips, which are laser engraved with the M logo.

The company said the new exhaust may be installed at any Authorized BMW Center at a price of $4,374 plus installation.
