Product Details

The MBRP S5146409 is a high-performance cat-back exhaust system engineered specifically as a factory dual replacement for Ram 1500 and Ram 1500 Classic trucks equipped with the 5.7L HEMI V8. This complete exhaust system delivers measurable performance gains, enhanced sound, and durable construction designed to outlast your stock exhaust.

Construction and Design:

Built from corrosion-resistant T409 stainless steel, this exhaust system is engineered to withstand the elements while resisting rust, dings, and dents. The system features precision jig manufacturing for consistent fitment and utilizes smooth mandrel-bent tubing that transitions from 3-inch diameter to 2.5-inch dual split rear configuration. Unlike crush-bent alternatives, mandrel bending maintains consistent inner diameter throughout each bend, ensuring unrestricted exhaust flow from the catalytic converter to the bumper exit.

Performance Benefits:

  • Gains of up to 5 horsepower and 7 ft-lbs of torque over stock
  • Improved exhaust flow reduces backpressure and enhances engine efficiency
  • 3-inch mandrel-bent tubing maximizes flow capacity
  • Direct bolt-on installation with no modifications required

Sound Characteristics:

This exhaust delivers a deep, smooth tone during cruising with an aggressive growl under acceleration—perfectly balanced for daily driving without excessive drone. The system provides noticeable sound enhancement over stock while remaining refined enough for comfortable highway travel.

What's Included:

  • Complete cat-back exhaust system with dual split rear exit
  • Two 4.5-inch OD mirror-polished stainless steel tips
  • All necessary hardware for installation
  • Lifetime warranty coverage

Compatibility:

  • 2009-2018 Ram 1500 5.7L V8 HEMI
  • 2019-2024 Ram 1500 Classic 5.7L V8 HEMI
  • Factory dual exhaust configuration only
  • Through stock bumper exit design

Part of MBRP's Armor Plus Series, the S5146409 is backed by a lifetime warranty and represents a significant upgrade in performance, sound, and durability over factory exhaust systems.
