Hey folks, this probably isn't the best delivery method, but here is a link to a 5-sec wav file you might enjoy. The sound is a run of the M Roadster running through 2nd and 3rd gear on the final straightway at Sears Point Raceway. You can clearly hear the Dinan intake noise kicking in at the end of second gear and the bass is provided care of Supersprint.
Hope you guys/gals like it:
