Bwana, this car has the ZPP exhaust option .. vacuum activated bypass .. I would not have ordered it, but it was on the car. It's fine for an economy car .. I have a car that roars pretty good already
Marc, garage is 10'3", I had to replace the stock 7' high door with a 9' and move the track up two feet. The track is about 12" from the ceiling. Vette is 49", bottom of lift rail is 54" at that locking tab, and the Cobra is 47". There is about 3" left over at the top to clear the door opener. You could get another 6" by moving the opener to the side or not using one, and another 6" by setting the track 6" from the ceiling.
This is a DirectLift ProPark 7, now superceded by the ProPark8.
