The rear of the exhaust system was most prone to damage as the moisture was blown backward and, in many cases, rarely dried up.  Most of us complained loudly when engine temperatures exceeded 180 degrees, saying that our engines would not last under the intense temperature pressure. That rise in temperature along with aluminized tubing just about put specialty exhaust shops out of business. Now we come to expect that an exhaust system will last the life of the vehicle, and in many cases, it will. (more…)
