Gibson 01-05 Chevrolet Silverado 2500 HD Base 6.0L 4in Cat-Back Single Exhaust - Aluminized

Gibson 315547 delivers a 4-inch cat-back single exhaust system with aluminized steel construction for 2001-2006 Chevrolet Silverado 2500 HD and 3500 models plus GMC Sierra 2500 HD and 3500 equivalents. This setup exits behind the rear tire for stronger acceleration, hill climbing, towing, and passing power while staying quieter inside the cab than stock. Dyno tests prove peak torque and horsepower from 1800-3000 RPM with average gains of 10-15 HP and 15-20 lb-ft torque.

Key Features

  • Performance Gains: Dyno-proven 10-15 HP and 15-20 lb-ft torque increases at low RPM for real-world towing and hauling power on Silverado and Sierra HD trucks
  • Single Side Exit: 4-inch piping exits behind rear tire to reduce drone and enhance ground clearance without sacrificing flow
  • Quiet Cab Operation: Gibson muffler design cuts interior noise levels compared to other exhaust systems while building low-end power
  • Bolt-On Design: Direct fit using factory mounting points with no welding or cutting required for fast professional results
  • Durable Build: Aluminized steel tubing resists corrosion and handles heavy-duty use with lifetime structural warranty

Product Notes

  • MPN 315547 designed specifically for 6.0L V8 engines in listed HD trucks
  • Aluminized steel provides rust protection for long-term performance
  • Ships standard ground in one oversized box weighing 68 lbs with dimensions 48 x 16 x 16 inches

Installation Notes

  • Professional installation recommended.
  • Bolt-on process takes 1-2 hours using provided hardware and clamps
  • Compatible with factory hangers and catalytic converters on all listed fitments
