TTI header install.

I myself will never put them in through the bottom again. It is probably easier to remove the radiator and act like you are pulling the engine, slide the headers in and let the engine back down. Your going to need to undo the motor mounts anyway so may as well let the trans loose too. I can almost guarantee this is the fastest way to do it compared to putting them in under the car because the front end needs to be jacked to the MOON for it to work out for you.
