Just asking to see how long it would take to install a CAT back and shorties on a 2006 Charger r/t. I know just the cat back is easy but is it a PIA to install the shorty headers? I figure if I was to do the cat back might as well do the headers at the same time. Also this car is from the north east so there is a bit of salty road love to the underside. When I had the motor mounts replaced they had to cut one of the bolts out.Just trying to see what I am getting my self into if I do the headers too. thanks for all the help.
