I can't speak for a 2008 Sport, but my 2007 Sport has the valve. There are no vacuum lines under the car, they (and the soleniod) are in the left side compartment in the trunk. Remove the two fasteners and you'll see the lines connected to the soleniod which is just near the left turn/brake light. The valve itself can be found in the right-side exhaust pipe. It's deep inside on the curved part, use a flashlight and shine into the right pipe, you'll see it. The car sounds great on idle like a V8 should!
