My buddy has a 60 catalina wagon with a similar set up and he had the same noise issue on the freeway. His daughters wouldn't ride in it. He already had the h pipe but he added 8 chamber mufflers and resonators. He also had a low brake pedal problem and he added an extra catch can to increase the vacuum capacity and that fixed his problem.
