If the exhaust pulses interfere with each other, then you have MORE noise and LESS engine horsepower. Again, more noise means less performance.

For those who want to throw a grenade into the mix - yes an Indy car has better performance and makes more noise. But which Indy cars have higher performance? The ones that make less noise. All else being equivalent - less noise means a better car, more horsepower, less pollution, longer vehicle life, etc. But you cannot tell that to the fools who just know more noise means a 'cool' car. So just laugh at them. They don't even remember principles taught in junior high school science.
