Here are 4 videos. The first is of my Old Custom Cruiser no exhaust. The other 3 are all of the same exhaust system but on 2 different cars. My Olds Custom Cruiser and my room mate Sarah's Buick Hearse. Her car has become the defacto home of most of my good parts from my car. BTW note the differences in the exhaust despite both using the same exhaust and both being Olds 350's. You can clearly hear the healthy cam that was in mine.
