I am most disappointed by v8 sounds when aftermarket exhaust is installed, they need to come to america and record some v8s with high flow exhaust or straight pipes. A 650hp camaro shouldn't sound like a skyline when I put on racing exhaust, I'm just putting on different exhaust not swapping a 6 cylinder into it. I live in a rural area and there are tons of pickups driving around with dual exhaust so I hear v8s everyday, I also drive a chevy silverado with a 5.3 v8. Just for an idea of how loud race cars are, I live about 15 miles away from two race tracks (half mile dirt ovals) when they race on calm nights I can clearly hear the screaming v8s outside my house, especially the sprint cars, they run around 800hp and the sound really carries a long ways.
