Here's the commercial that aired in 1970!kirban 2 cents worth
BINGO
WINNER...
Send me pm with list of what you won in the past.
This was offered only on the 1970 GTO....a tricky set up vacuum controlled that basically allowed straight out exhaust thru the muffler...problem was this did not sit too well with the state of Pennsylvania laws emissions whatever and it got canned early on....
Actual count that saw actual production was around 275 units....more recently it has been reproduced for those cars and I know Corvette on I believe the 2006 ZO6 has a similar system and has it on the later Corvettes probably as an option,
For a 1970 GTO owner that was the Holy Grail if you had an original one of these systems....the pull handle was on the same bracket as the ram air knob that opened the flaps for the ram air set up. Primitive by todays standards but in its day was the hot set up....
