The car catalytic converter calamity concluded contentedly (a 6 C sentence!). The good guys at Master Muffler on 6700 South State Street in Salt Lake City had the partially cut exhaust pipe patched and welded within 15 minutes, and the best part is they did the work for FREE. I'm amazed that that kind of service still exists. A muffler shop in Utah restores my faith in America. Thanks MM guys!
