So I took the Blazer for the first real drive ever. This afternoon I drove it down to a friends house about a mile down the road. Drove quite nice on the road, but the tires sing! Not just a hum!! I maybe got it up to around 50MPH and it was loud! They sing over the exhaust that leaks out of many holes before and after the mufflers. The hole in the back of the bed make the effect even worse!
Anyway, it was an enjoyable drive. A new exhaust is definitely on my TO DO list!!
