Product Details

The Diamond Eye Manufacturing K4378A is a complete 4-inch aluminized steel DPF-back exhaust system engineered specifically for 2015-2016 Ford Super Duty trucks equipped with the 6.7L Power Stroke diesel engine. This single exit exhaust system connects directly behind the diesel particulate filter (DPF) and provides improved exhaust flow while maintaining emissions compliance.

Key Features:

  • 4-inch diameter mandrel-bent aluminized steel tubing for maximum flow and corrosion resistance
  • DPF-back design retains factory emissions equipment for legal compliance
  • Single side exit configuration for clean, OEM-style appearance
  • Precision-engineered for direct bolt-on installation with no cutting or welding required
  • Mandrel-bent construction eliminates restrictive crush bends found in OEM systems
  • Includes all necessary hardware, clamps, and hangers for complete installation

This exhaust system delivers reduced backpressure for improved throttle response, enhanced fuel economy potential, and a deeper, more aggressive exhaust tone while maintaining the factory DPF and emissions controls. Diamond Eye's aluminized steel construction provides excellent durability and protection against corrosion at a value price point.

Could not be any easier, if this works out you will receive a lot of business thru my referrals.

Very nice website!

Ordered 4 race ramps flatstoppers for winter storage of my Dodge Viper. Product prevents flat spots on auto tires that are stored more than 30 days. Order process was extremely easy, product was promptly shipped. I'll definately do business with Autoplicity in the future.

So far great, no problems. Received order on 04/21/2015
