Does the exhaust valve open larger when VTEC kicks in? Or maybe it's just the intake?

Depends on the version of VTEC. All DOHC VTEC systems change the timing and lift on both the intake and exhaust valves. Most of the SOHC VTEC systems only affect the intake, although the newer J37A4 has VTEC on both the intake and exhaust.
