How to Find the Perfect Balance of Sound and Flow

  • Install a tubing size that your motor needs and nothing bigger.
  • Be realistic when choosing a muffler—if you plan on commuting, don’t use a race muffler.
  • Don’t over-buy. It’s easy to lose horsepower by bolting an expensive “racing” exhaust on a stock engine. Instead, choose an affordable kit that’s designed for stock applications—the power gains will surprise you.
