Product Details

The Flowmaster 717873 Flow FX Cat-Back Exhaust System delivers enhanced performance and an aggressive sound upgrade for your vehicle. This complete system features Flowmaster's innovative FlowFX straight-through performance muffler design that produces a deep, satisfying rumble with minimal interior resonance, giving you the perfect balance of sound and refinement.

Performance Benefits:

  • Gains of 6.7 horsepower and 6.5 lb-ft of torque over stock exhaust
  • Straight-through muffler design improves exhaust flow and reduces backpressure
  • Mandrel-bent 16-gauge 409 stainless steel tubing maximizes exhaust velocity

Quality Construction:

  • Premium 409 stainless steel construction provides excellent corrosion resistance
  • Large 4.5-inch black ceramic coated stainless steel tip adds aggressive styling
  • Factory-styled hangers mount in stock locations for proper fitment
  • Complete hardware kit included for straightforward installation

Backed by Flowmaster's Lifetime Limited Warranty, this cat-back system offers proven durability and long-term performance. The mandrel-bent tubing maintains consistent diameter throughout each bend, ensuring optimal exhaust flow and power delivery across the RPM range.
