everything sounds good to me except the mac headers, especially there long tube ones. The flanges suck that bolt to the heads instead of a solid one piece design each port has a flange which sucks, know a few people that have some and cant stand them. plus the clearance is a pain around steering shaft, buddy had to take a hammer to his headers.

i never have had a problem with mine and the fit is great but you are right the one peice design does suck

i say do the first option with the 3" catback and 3.5" tips. thats what I am thinking about doing. I have the mac 1 5/8" long tubes and damn they did suck but once on, i have had no problems. I am thinking of running the 1 3/4" long tubes, if you are making or will make big hp like that you should too.

550HP???? What's your setup?

If your making 550hp then I would say 1 5/8" minium if not 1 3/4" and 3" on the Pro-Chamber and cat-back but me personally I would just keep the 3" tips not 3.5".
