This complete cat-back system features full stainless steel construction throughout, ensuring long-lasting durability and resistance to corrosion in all weather conditions.

Performance Features:

  • Mandrel-bent 3-inch dual tailpipes for maximum exhaust flow and reduced backpressure
  • Dyno-proven gains of up to 10 horsepower and 13 lb-ft of torque
  • Aggressive, deep tone both inside and outside the vehicle for that authentic muscle car sound
  • Large 4-inch black ceramic coated stainless steel tips for a bold, finished appearance

Quality Construction:

  • 100% stainless steel mandrel-bent tubing resists rust and maintains consistent pipe diameter through bends
  • Precision-engineered for direct bolt-on installation with all necessary hardware included
  • Designed for easy at-home installation with basic hand tools
  • Backed by Flowmaster's Lifetime Limited Warranty for peace of mind

The Flowmaster Outlaw series is engineered for drivers who want maximum sound with no restrictions. This cat-back system replaces everything from behind the catalytic converters to the rear bumper, transforming your vehicle's exhaust performance and sound character.
