“When my vehicle was warming up I noticed two plumes of smoke coming from the muffler area. One plume was the tailpipe and the other was shooting straight down from underneath the vehicle. Upon inspection I found a whole in the bottom of the muffler. There is no denting or impact damage near the hole. There is exhaust stains on the muffler ranging from the hole towards the rear of the vehicle. The exhaust stains show evidence that the whole and the exhaust leaking out has been taking place for quite some time. It is obvious the muffler rotted.”
