Diamond Eye Performance — Frequently Asked Questions

Will a Diamond Eye exhaust improve performance?

Yes. The mandrel-bent design reduces backpressure, typically improving spool-up, throttle response, and overall power.

Which material should I choose: aluminized or T409 stainless?

Aluminized offers great value in dry climates. T409 stainless provides superior corrosion resistance—ideal for salt, snow, or long-term durability.

Is installation bolt-on?

Most Diamond Eye systems are direct bolt-on with included clamps/hardware and factory-style hangers. Always confirm wheelbase and cab/bed configuration.

Will a Diamond Eye system be too loud for towing?

No. Diamond Eye systems deliver a deep, controlled tone designed to minimize drone while maintaining a strong diesel sound.

Do I need tuning after installing a Diamond Eye exhaust?

For DPF-back and most cat-back systems, no tune is required. Turbo-back or off-road configurations may require custom tuning and are for competition/off-road use only.

Can I keep my factory emissions equipment?

Yes. Diamond Eye offers emissions-compliant DPF-back and cat-back options that retain factory emissions components. Check local regulations before modifying exhaust systems.
