Service Engine light came on. The code came back as p1173. I know that one of the cats is leaking because i got under my truck while the car was running and saw/felt exhaust from the cat and could see where it had be punctured or bent in. Could this be throwing the code? As soon as i got the truck the passenger side header was replaced also.

Most likely not but the bad cat should be replaced first before trying to fix the 1173.
