i have the mac headers w/ ypipe


i have a question on the cat

once the headers are bolted on, what did u guys do with the cat, u have to have flange rewelded in side the cat

any help will be greatful


oh, the catback is hooker

 

the cat is either welded or a flange out on - the flange make the cat removable if you want to use an off road pipe from time to time.
