Valved design allows drivers to select between refined cruise tone and full-throttle aggression via OE valve actuation.

Decibel-tested acoustic tuning eliminates drone points while delivering purposeful low-end character on acceleration. Carbon fiber tailpipe surrounds integrate seamlessly with G63 styling.
