How an aspirated car should sound
 

The car in question is an ex-works BMW M3 grA being driven in the Basque Rallying Championship, and sideways, BTW

"and to think that is the sound othe air going INTO the engine" - JC

Glorious induction growl! Individual throttle bodies are so cool, too bad so little cars have them.

At the beggining it reminds of an M3 CSL :-D

^ That's because it also has a large airbox and ITB's ;-)
