Manufacturer's Warranty — Diamond Eye Performance

Diamond Eye Performance does not publish a consumer warranty. There is no warranty, returns or terms page anywhere on the manufacturer's site, and no coverage period appears in its published material — the only policy page it has ever had, Conditions of Use, has been marked “Under Construction” since 2011. Any warranty length quoted for Diamond Eye elsewhere comes from a reseller, not from the manufacturer, so we do not repeat a figure here. Diamond Eye manufactures its own exhaust components and will consider a genuine manufacturing defect, but with no published term we will not state one on its behalf. Contact us with your part number, proof of purchase and clear photos of the fault and we will take the claim up for you.

Warranty terms are set by the manufacturer and may change. Contact us if you need help with a warranty claim.
