The MagnaFlow Competition Series Cat-Back Performance Exhaust System 16674 is engineered for drivers seeking an aggressive, attention-grabbing exterior exhaust note with a moderate interior sound profile. This system replaces the factory exhaust from the catalytic converters back, utilizing fast-flowing 3-inch mandrel-bent piping to reduce backpressure and improve performance.

  • 3-inch mandrel-bent main piping for high-velocity exhaust flow
  • Dual straight-through mufflers deliver a deep, resonant tone
  • Dual split rear exit with 4-inch polished welded-on double-wall angle-cut folded edge tips
  • 100% durable and corrosion-resistant stainless steel construction
  • CNC precision robotic manufacturing for exact fitment
  • Direct-fit design based on 3D scanning of the S197 chassis
  • Manufacturer Part Number: 16674

Each kit includes the necessary hardware for installation. This performance exhaust is backed by MagnaFlow's limited lifetime warranty. Please check local noise regulations to ensure compliance before installation.
