installing Bassani equal length headers on 99 cobra

Hey can anyone who has installed bassani equal length headers . I just bought them and I was woundering in the directions they say nothing about welding is there any involved or is it just a straight bolt on. And did you have to do any certain mods to car to get them to fit.
 
From everthing I've heard and seen there is no welding, direct bolt on. Some you will have to take out the K member and support the motor to put them in. Others you have to take the starter out and 1 motor mount bolt on the pass side, Jack the motor up about an inch or more ( be sure to disconnect you CAI) and you can get the header in, the driver side disconnect the steering arm and it should painfully go in.
The more ppl I talk to that have long tubes, the more I hear horror stories about installing them.
