In Thailand louder exhaust are crucial and of the reasons I fitted a Scorpion on mine. I drove the car (until recently) to work most of the time, and in Thailand battling for space with thousands of scooters and maniac school vans and mini bus drivers is a daily challenge.
What persuaded me to upgrade my exhaust was the fact I heard on many occasion a motorcycle coming from behind somewhere. It's hard to tell where because the sound is low and pretty much none directional. But while driving at near stationary speeds bumper to bumper, It gave me time to look around and make room.
