Any idea what this sound difference could be? Mine has a weird "grinding" type sound, where as a friends stock c5 doesn't. Mine has a&a SC setup on it. i put my ear right up the the SC and it isn't as prevalent as when i put my head under the front of the car.

any help?

some engine accessory or pulley with a bad bearing, possibly.
