1970 Pontiac GTO exhaust

Buddy of mine put up a sound clip of his Yamaha R6 streetbike, so i thought i'd just 1-up him and upload a clip of my 1970 GTO with it's half assembled Summit Racing Exhaust :) ill be switching it out for a Flowmaster system as soon as i have $500 to burn and a free weekend to install it. it has a temporary 350ci V8 right now while i rebuild the factory 400ci engine, so it WILL be louder in the future. sorry about the camera falling over at the end, that 350 pumps out a lot of Exhaust. knocked it right over at about 3500 rpm

1970 Pontiac GTO VOE "The Humbler"
A new and short-lived option for 1970 was the Vacuum Operated Exhaust (VOE), which was vacuum actuated via an underdash lever marked "Exhaust." The VOE was designed to reduce Exhaust backpressure to increase horsepower and performance, but it also substantially increased Exhaust noise. The VOE option was offered from November 1969 to January 1970. Pontiac management was ordered to cancel the VOE option by GM's upper management following a TV commercial for the GTO that aired during Super Bowl IV on CBS January 11, 1970. In that commercial, entitled "The Humbler," which was broadcast only that one time, a young man pulled up in a new GTO to a drive-in restaurant with dramatic music and Exhaust noise in the background, pulling the "Exhaust" button to activate the VOE and then left the drive-in to do some street racing. That particular commercial was also cancelled by order of GM management. Approximately 230 1970 GTOs were factory built with this rare option. A few mufflers have been "Hand-made" for the remaining cars; this occurred in 2006 and 2007.
