Why Buy Diamond Eye from CPP Diesel?

Curated inventory of Diamond Eye best-sellers and hard-to-find parts
Fitment-first listings with clear platform/year/engine coverage
Fast shipping and diesel-savvy support from real enthusiasts
One brand, many choices: aluminized for value or T409/T304 for longevity

Helpful Notes

Material: Aluminized = value; T409 = durable daily-driver; T304 = premium corrosion resistance.
Sound & Flow: Muffler-equipped systems are quieter; straight-through or “no-muffler” kits are louder and flow more.
Fitment: Verify bed length, cab configuration, and wheelbase; some kits differ by these specs.
Compliance: Always check local and state regulations before modifying emissions-related components.

Diamond Eye Performance FAQ

What’s the difference between aluminized and stainless (T409/T304)?

Aluminized steel offers strong value and solid corrosion resistance in mild climates. T409 stainless resists rust better for daily drivers, while T304 is a premium choice with the best corrosion resistance and finish.

Will a larger-diameter exhaust help a stock truck?

Moving from restrictive factory tubing to a mandrel-bent system typically reduces backpressure and EGTs. Gains vary by platform and tune, but throttle response and turbo sound often improve.

Do Diamond Eye systems include clamps and hangers?

Most kits include required clamps and OE-style hangers. Check the product listing for exact contents to ensure a smooth installation.
