100% accurate. Worked with a guy that lived about 1/2 from the plant front door. Started the truck, drove it 1/2 to work, 1/2 mile home. Condensation build-up inside the muffler. The exhaust system never got hot enough to burn off the inside of the system. Consequently, he was going thru mufflers every 18 months.If you're looking for some indication on how long the exhaust system may last, I'll offer up some hints. Firstly, as they say, your mileage may vary. Drive more highway miles each day and your system will laaaaassst! I drove my 2001 Elantra over 200k miles with the original exhaust system and NEVER had a problem. But, there were lots of highway miles in that 200k. If, on the other hand, you drive more city or stop and go miles, then you'll probably experience a shorter lifespan.
