Product Details

The Magnaflow 12909 is a high-performance universal muffler engineered to deliver exceptional flow and deep, aggressive exhaust tone. This straight-through design muffler features premium stainless steel construction for maximum durability and corrosion resistance in demanding conditions.

Key Features:

  • 3.5-inch inlet and 3.5-inch outlet for maximum flow capacity
  • Straight-through perforated core design reduces backpressure and increases horsepower
  • 100% stainless steel construction ensures long-lasting performance
  • Continuous straight-through fiberglass matting absorbs unwanted interior resonance
  • Universal fit design adapts to a wide range of custom exhaust applications
  • Oval body configuration for versatile mounting and ground clearance

Magnaflow's straight-through design allows exhaust gases to flow more freely compared to restrictive stock mufflers, resulting in improved engine efficiency and a distinctive performance sound. The high-quality stainless steel construction resists rust and corrosion, making this muffler ideal for daily drivers, weekend warriors, and racing applications alike.
