Flowmaster Outlaw Race Mufflers

Product images may differ from actual product appearance.

Designed for racing, the Outlaw Series showcases Flowmaster's smallest and lightest race mufflers. When attached directly to collectors, Outlaw Mufflers generally produce more power than open headers while calming that open header sound. They're intended primarily for race situations where a muffler is required yet has no decibel restrictions. Suitable for some turbo diesel applications.

Features
  • Maximum horsepower and torque with minimal sound reduction
  • 16-gauge aluminized steel or 409S stainless steel
  • Short or standard lengths
  • Round case is great for limited-space installation
  • No internal packing so nothing blows out
  • Welded for durability
