MHP Stainless-Steel Muffler

• A quieter aftermarket muffler that still projects a nice V8-sounding rumble
• *Should expect to see instant gains of 1-2 MPH and 200-400 RPM 
• Comes with mounting brackets and hardware
• Includes free shipping to the lower 48 states

*Only to be used with Big Block Vanguard Engines (25-40 HP models)

*Gains are totally dependent on hull, load, prop, drive, location, conditions, etc. These are just the gains our previous customers have seen and relayed back to us.
