Why buy an aftermarket muffler if you can make your bike louder simply by removing the baffles? Proponents of baffle removal also claim that by removing baffles you’re allowing your exhaust to flow more freely and thus increasing performance.

The difference between the sound of an explosion in your piston and a firework exploding is that the explosion inside your motor has its sound waves absorbed and modulated by your exhaust. Inside your bike or car motor, a similar thing is happening every time your spark plug fires. They’re so loud because there’s nothing around them to absorb the sound waves. There’s a really loud bang – and this sound is caused by a sonic boom from the rapid expansion of gases in the explosion.
