Dougs headers beating me with a ball bat
I installed my TTIs with the front of the car hoisted about 4' in the air. I had already installed a 2x4 between the motor mounts so the motor is lifted(I did that on each side as I went). z-bar has to go. The headers installed from underneath the car to there proper position. I don't know about the Dougs but on the drivers side the TTI has a separate tube that mounts in later (the back exhaust tube) which makes things easier. On the passengers side I had to shave the scattershield until the header slid past it to the motor. It wasn't really that bad.
