AR Headers-Is driver's side header installed from top or bottom?
 

The emission pipe fell off so I have to remove the driver side header to have it fixed. I installed them with the engine through the bottom so I never installed just the headers. Thanks

Yes, through the bottom. You may have to remove the sterring knuckle for clearance, but otherwise, that should be it.

Same here, both sides went in through the bottom. I had to loosen the steering knuckle too.

X3 - from the bottom. I didn't have to touch my steering, though. I kept jacking the nose of the car up, and once the front hub was ~28" off the floor the header slid right on up into place.

Thanks for the help. I did do it from the bottom and did have to move the steering shaft/knuckle.
