Complete Manifold-Back Exhaust: Accurate vs TTi

I don't think anybody makes the one year only 70 Dart 340 exhaust tips with oversized inlet pipes. You used to be able to get them but the small company went out of business. I've been trying to get Accurate to make them for years without success. In the old days - 1980s - we used to put a piece of exhaust pipe that matches the rest of the system over the little inlet of a factory tip, mark the tip, cut off the tiny inlet and weld the pipe to the tip. if you wanted it removable, you used a stub of pipe that had an ID the same size as the tailpipe OD so it could be slipped inside and clamped.
