time for headers... Need help !

My Hookers has the drive link going through the header itself. Does the TTI eliminate that? From the pictures I've seen they do but I was just wondering if that is correct.

When I get the TTIs is it possible to install them without having the car on a lift? If I have to I will saw all the Hookers off to get them out. Just wondering if a shade tree mechanic like myself can get the car high enough to install the TTIs. I realize I will have to undo the motor mounts, starter etc..
