02 Suburban, True Dual Race Exhaust revs and take-off
My 2002 Suburban with True Dual Eastern Race Cats, Dual Flowmaster 10-Series single-chamber mufflers, and 4" EchoTips... Just start-up, a few revs, and a slow take off. Pretty much a 360-degree tour of the outside of my truck. I had taken more videos including normal acceleration and drive-by, and then flooring it from a dead stop and fly-by but it was too windy on the mic... will redo them asap and post as well
