Warranty Coverage

All products manufactured by Valvetronic Designs are guaranteed to be free from manufacturing defects in materials and workmanship at the time of sale. A manufacturing defect is defined as any characteristic of the product that arises during the manufacturing process which impairs its usability for the purposes for which it was designed and manufactured.

Products are guaranteed to fit and function as designed on their intended vehicle application, provided the vehicle has not been modified or incurred structural damage. Sound or tone is not a warrantable or returnable issue, as exhaust sound is subjective and not considered a defect.
