I do not know how that guy can hear afterwards, had a volvo, had the muffler fall off, thought I had the entire rebels MC gang next to me ear, they are loud engines (louder than most other big fours anyway)
On the way back from sydney (to brisbane) i had my exhaust break apart at the cat, the cat hit the floor and turned the inside honeycomb about 90 degrees enough to stop all flow.. I took off the exhaust and drove the next 600kms in the most horrible noise i can think of.
