Bentley Edinburgh took to Instagram this week to show off their dealer install sport exhaust for W12 Continental GTs. Several of our readers asked about this option after we previously profiled the available sport exhaust for the Continental GT V8. There are many options available from aftermarket manufacturers for exhaust but this is the first kit we’ve seen from authorized dealers. No word if this kit is available in the U.S. Regardless, enjoy the sound clip embedded below of a mean sounding Bentley GT Speed!
