Dyno Discipline: A Silly-Straw Exhaust Meets a Sober Verdict on Horsepower

A builder twisted an exhaust pipe into the loops of a novelty straw, borrowing the internal geometry of a Tesla valve — a device built to steer liquids one way, never combustion gases. Put on a dyno, the curling design did what the laws of exhaust flow would suggest: it choked output rather than adding any benefit. The result stands as a clean, measured argument for why straight, simple tubing still wins over a clever shape.
