Product Details

The Diamond Eye K4376A is a complete 4-inch DPF-back exhaust system engineered for 2011-2014 Ford F250/F350 Super Duty trucks equipped with the 6.7L Powerstroke diesel engine. This single-exit exhaust system delivers improved exhaust flow, enhanced performance, and a refined exhaust tone while maintaining emissions compliance.

Key Features:

  • 4-inch mandrel-bent aluminized steel construction for maximum exhaust flow and durability
  • DPF-back design installs behind the factory diesel particulate filter for emissions compliance
  • Stainless steel muffler with perforated core produces a deep, aggressive tone without excessive drone
  • Single passenger-side exit configuration with polished exhaust tip
  • Complete bolt-on system includes all necessary clamps, hangers, and hardware
  • Fits crew cab and super cab configurations in all bed lengths (excludes single cab models)
  • Mandrel-bent tubing eliminates restrictions found in factory crush-bent exhausts

This exhaust system helps reduce exhaust gas temperatures (EGTs), improves fuel economy, and provides modest gains in horsepower and torque. The aluminized steel construction offers excellent corrosion resistance for long-term durability in harsh driving conditions. Diamond Eye's mandrel-bending process ensures smooth, consistent bends that maximize flow without creating turbulence or backpressure. Made in the USA with Diamond Eye's commitment to quality and precision manufacturing.
