Carbon fiber, black coatings, tip finishes and moving parts such as valves and actuators carry a one-year term, and appearance blemishes from weather, road hazards, lack of maintenance or temperature extremes are not covered. When Borla's inspection confirms a defect, Borla repairs or replaces the part at its option. The warranty does not pay for removal or reinstallation, does not apply to parts damaged by accident, abuse, misuse, misapplication or modification, and does not cover sound level, because sound is a matter of taste. \u003cstrong\u003eShipping.\u003c\/strong\u003e The carrier and ship method are set by the size and weight of the carton when the order is placed; long exhaust systems ship in oversize cartons. \u003cstrong\u003eInspect on delivery.\u003c\/strong\u003e Please inspect the carton and the part as soon as it arrives, before installation, and report any shipping damage to us right away so we can make it right.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReturns.\u003c\/strong\u003e Unused items in their original packaging can be returned within 30 days of delivery.
