1975 Dart 318 (sorry but it's a4 door) Just want to say THANKS in advance the help!!

Any pics?? I love 75 darts of any kind. I have a 75 dart 2 door with a slant six but I always liked 4 doors as well because the original darts are just great cars. :)
Don't have her back from getting tuned yet, but when I do I'll post some for you. It's a longer journey than I wanted but when I fired it up Sunday for the first time since headers were installed and no exhaust I about s@!t my pants, LOL! It went from sounding like my grandmas pinto to a fire breathing dragon!! I'm just debating on what to do with the exhaust now!?!? I want it to sound good but don't want to draw too much attention from the tuner guys until I get next to them. She should be decent enough on gas to be daily driver, at least I'm hoping.
