This BMW X4 M40i Looks Great But Doesn't Sound So Great! We Upgrade With An Incredible dAHler Valved Exhaust System & It Rips!

Modern day M-Powered cars really do look incredible, drive incredibly well but due to the UK / EU regulations on emissions and sound, the sound-track is something to be desired.

The owner of this X4 really wanted a more aggressive tone from his system as well as the ability to sound as OEM as possible for quieter / longer drives!
