Products in Excellent condition look brand new — with no physical flaws, scratches or scuffs — and include all original parts and accessories. The product will be in its original packaging or a suitable replacement box.
Open-Box - Satisfactory
Products in Satisfactory condition show minor to moderate signs of use that affect cosmetic appearance but have no impact on performance. A satisfactory product does not include dents, chips, cracks, or deep scratches. It may not contain the original packaging or some parts and accessories.
Open-Box - Fair
Products in Fair condition operate as intended, but show more significant scratches, dents, or chips. For example, an exhaust returned to Dennis Kirk with a dent or large scratch that doesn’t affect the product's performance. It may not contain the original packaging or some parts and accessories.
