Did anyone read that car and driver article about this car? It talked about the engine subwoofer which was a pressurized tube leading from the block to the firewall. The tube had a drumhead on the firewall side which vibrated wih a raw deep sound as you cranked up the rpms. I think that this might change the sound for the meatier, but its almost cheating. I think an engine, espescially a BMW engine, should sound good on its own. Anyone actually heard this in action? What are your thoughts?
