My car has "cutout valves" on the exhaust which can bypass the muffler (making it louder), and I've noticed an interesting phenomenon: the car actually seems faster (to it's occupants) when it's in the quieter mode. I've dynoed it in both modes, the torque and horsepower curves are nearly identical, so it's not actually faster.

- tlrobinson 12y agoI like the sound (and I'm shameless about it).
