âś… Frequently Asked Questions (FAQ)

What makes Diamond Eye exhaust systems different?
Diamond Eye exhausts are made in the USA and use mandrel-bent tubing to maximize exhaust flow. They offer noticeable gains in performance and sound quality for Cummins diesel trucks.

Do Diamond Eye systems fit both 5.9L and 6.7L Cummins?
Yes, CPP Diesel carries Diamond Eye kits for both 5.9L and 6.7L Dodge Ram Cummins engines. Just select the year and model of your truck when shopping.

Should I choose aluminized or stainless steel?
Aluminized kits are affordable and great for dry climates. Stainless steel is corrosion-resistant and ideal for long-term durability or trucks in snowy, salty, or wet environments.

Will I need to tune my truck after installing a Diamond Eye exhaust?
Most bolt-on Diamond Eye exhaust systems do not require tuning. However, if you delete emissions components (off-road use only), a tuner will be required.

Can I install a Diamond Eye exhaust at home?
Yes. Most kits come with direct-fit hardware and are designed for driveway or garage installation with common tools. Always follow safety precautions.
