Our new line of Wrap Around Pitts Mufflers are designed generally for inverted mounted engines. Each muffler is made to replace the standard muffler using the existing mounting bolt location and exhaust pattern. The Wrap Around Pitts Style Mufflers are light weight, offer large expansion chambers to help reduce noise and are TIG welded for strength. Available for engines .90cc & up. Since each muffler is made when you order it we can also customize the muffler to your needs.
