Product Details

The Diamond Eye Manufacturing K3122A is a complete 3-inch cat-back dual exhaust system engineered specifically for 2014 Chevrolet Silverado 1500 trucks equipped with 4.8L or 5.3L V8 engines. This mandrel-bent exhaust system delivers improved exhaust flow, enhanced throttle response, and a deeper, more aggressive exhaust tone compared to restrictive factory exhaust systems.

Key Features:

  • Mandrel-bent aluminized steel construction for smooth, unrestricted exhaust flow
  • 3-inch diameter tubing maximizes performance gains
  • Dual exhaust outlet configuration for enhanced appearance and sound
  • Cat-back design retains factory catalytic converters for emissions compliance
  • Direct bolt-on installation with all necessary hardware included
  • Precision-engineered fitment designed specifically for 2014 Silverado 1500
  • Aluminized steel finish provides corrosion resistance and durability

Diamond Eye Manufacturing utilizes CNC mandrel bending technology to create smooth, constant-diameter bends throughout the exhaust system, eliminating the crimping and flow restrictions found in crush-bent factory exhausts. This cat-back system is designed for truck owners seeking improved performance, fuel efficiency, and an upgraded exhaust note without sacrificing reliability or emissions compliance.

Ordered a couple of items. The first was a air intake kit. I had put in all my info for my truck and chose one from the list to order. Won't fit. Called to tell them and they asked if I had called manufacturer...ummm no. Said I needed to contact them to verify wrong part. They were closed, so went to website. The part they sent me was a universal fit- for cars, not trucks, but did find right model- $90 more. Called back autoplicity and was told I need to go through email to get an RA# to return wrong part- site says I can call. Been on hold for over 20 mins and still waiting. Hope the Nerf bars I ordered fit! Update- they called me back, got my RA#. Very pleased with how Nick handled things- it was what I expected the first time. He verified the NERF bars will fit and will be changing the website so the universal intake does not show on list for vehicles with larger air outlets. Changing my rating to show my satisfaction with how it was eventually handled.
