I just made a Google search, but can't find anything conclusive on what brands make street legal long pipe headers.
Are these street legal versions any better than say mid pipe headers? A mustang website states that "If you need catalytic converters for a lenient emissions county, you can get by with mid length headers and high flow catalytic converters." Are these almost as good as long pipes, or is there no point in getting them? I'm assuming that generally it is a good idea to get new headers with a new exhaust system, am I right? Also, a muffler is just what gives certain cars a different exhaust sound, right? I.e. Fart Cans.
