Product Details

The Diamond Eye K3330S is a complete 4-inch cat-back exhaust system engineered specifically for 2011-2013 Ford F-150 EcoBoost trucks. This system fits all cab and bed length configurations, providing a universal solution for EcoBoost-equipped F-150 owners seeking improved exhaust flow and performance.

Key Features:

  • 4-inch mandrel-bent 409 stainless steel tubing for maximum flow and durability
  • Complete cat-back system replaces restrictive factory exhaust
  • Precision-engineered fitment for all 2011-2013 F-150 EcoBoost cab and bed configurations
  • Mandrel bending maintains consistent pipe diameter throughout bends for optimal exhaust velocity
  • 409 stainless steel construction resists corrosion and provides long-lasting performance
  • Designed to unlock additional horsepower and torque from the 3.5L EcoBoost V6
  • Deeper, more aggressive exhaust tone compared to stock

Diamond Eye Manufacturing utilizes CNC mandrel bending technology to create exhaust systems with smooth, consistent bends that eliminate turbulence and restriction. The 4-inch diameter provides substantial flow improvement over the factory exhaust system, allowing the twin turbos of the EcoBoost engine to breathe more freely. This system is ideal for both stock and modified EcoBoost engines, supporting increased boost levels and performance upgrades.

Great site! Very easy to find what I needed and quick checkout. I'll be back!

Good web purchase

The price is good, easy to fill out the required information, I hope the shipping is fast, paid for 2 days over night, need the part now.

THE EASIEST AND FASTEST SHOPPING I HAVE EVER DONE.THANKYOU

Cool

Good fitment info and easy to follow menus.

Good selection, easy installation. The only problem was the stake pocket bolts for my 2015 F150 had to be modified. They were too long. Not sure why. I was positive that I selected that year when I ordered.

Very fast website and easy to use.

Everything was easy, from finding to ordering my parts.

Prices have gone up in the last month. Still it was an easy shopping experience.

Easy to buy. Best price
