Jenny Merwin San Jose, California - 1996 Honda Prelude
She drove her boyfriend's car, for about 40 miles, and tet RPM's get over 5,000 on one turn. Boyfriend says that put stress on engine, which in turn wrecked the catalytic converter. Is this true? No, he's nuts. There's no engine speed that would ruin the catalytic converter. Age was a much more likely culprit. Dump the boyfriend or tell him to be nicer!
