Product Details

The Magnaflow 11148 is a high-performance straight-through muffler designed to reduce backpressure while delivering a deep, aggressive exhaust tone. This compact muffler features a straight-through perforated core wrapped in sound-absorbing stainless steel mesh packing, allowing exhaust gases to flow freely for improved performance and throttle response.

Key Features:

  • 2.25-inch center inlet with dual outlet configuration for versatile installation options
  • Compact oval body dimensions: 3.5 inches x 14 inches x 7 inches
  • Straight-through design maximizes exhaust flow and minimizes restriction
  • Stainless steel construction resists corrosion and provides long-lasting durability
  • Perforated core with acoustical packing reduces drone while maintaining performance tone
  • TIG-welded construction ensures leak-free performance

Ideal for custom exhaust builds, this Magnaflow performance muffler delivers the perfect balance of sound quality and power gains. The straight-through design is engineered to support high-flow exhaust systems on trucks, SUVs, and performance vehicles.
