High Performance Mufflers Dyno Tests

June 21, 2010 natureguy Noise Pollution

Do high performance mufflers make horsepower gains or are they marketing pipe dreams? They advertise that their mufflers increase performance quite dramatically from a stock muffler, but never seem to have dyno tests to provide proof. They often only quote muffler flow rates in comparison to a “stock” muffler. The question should then become how much flow is required and how much does more than good enough make? Finally, Horsepower TV on Spike TV (episode HP2010-07) did a dyno comparison test of some Cherry Bomb mufflers for sound levels and horsepower.
