Well my '90 accord needs a new muffler. I can't complain, it is the original. Looking under the car I'm encouraged to see it is designed to fit the intermediate tailpipe with a bolted flanged connection rather than clamps or welds. Tempts me to buy a muffler and replace myself. Anyone done one of these. Should I expect that a thourough soaking of the nuts with liquid wrench will get them to break loose? Frank
