ELI5: Explain Like I'm 5

Tuned exhaust

A tuned exhaust is like a special straw that helps a car or motorcycle run better. Just like how you take a big breath through a straw, the engine takes a big breath through its exhaust pipe. The straw is designed to be a certain length and shape to help the engine breathe in and out more efficiently, like a runner taking deep breaths during a race. This helps the engine make more power and go faster. Imagine blowing up a balloon with a narrow straw versus a wide one – you have to work harder with the narrow straw, which is what happens to the engine without a tuned exhaust. The tuned exhaust helps the engine work less and go faster!
