Are you removing your cats from the X-pipe?
I just welded a bolt in the hole on mine. Those lines run from the pump to the back of the heads. There is a junction block on each head with a bolt in it. Remove them. Then to fill the hole in the back of the heads just cut the lines off of the junction block and flip them over and bolt them back on making sure you have the holes completely covered with the block.
