Author's Note: How much horsepower does a performance muffler add?

Can we talk for a minute about the horrors that are clamp-on fake exhaust tips? No one really believes that a 15- or 20-year-old compact hatchback has a full performance exhaust that's so big, a bodybuilder could insert his arm up the elbow. Especially when the car still sounds terrible -- wheezing like a three-pack-a-day smoker. And what for? To entice competition that the car can't handle?

For the most part, it seems like those days are over ... at least where I live. Or maybe it's that I'm too old and jaded to notice it anymore. But I've always believed it's better to just drive the car completely stock than to waste money making it look like it has been modified. It was a tacky aspect of car culture back when a considerable segment of the population might have been fooled -- it's even worse now that the trick has run its course.
