      Warranty Info

      BLUEFLOW specializes in superior catalytic converter and exhaust technology and has spent the past 20+ years earning its reputation as a market leader. BLUEFLOW Catalytic Converters combine efficient industrial design to produce a product that exceeds, rather than meets, the highest standards of product performance and efficiency in the industry. BLUEFLOW uses Ceramic substrates with different combinations of cell density and wall thickness to meet vehicle specific requirements.

      BLUEFLOW warrants that all Performance Products are free from defects. Most of exhaust products are warranted against blowouts and defects in material and workmanship for as long as the original purchaser owns the vehicle on which it was originally installed. The warranty is void if the exhaust products are not installed properly on the vehicle for which it is designed.

      This warranty does not apply to any exhaust product which has been installed on any commercial or racing vehicle or which has been improperly installed, altered, or subjected to misuse or damage from accidents. Also, cost of labor and any additional parts required to complete installation of a replacement product are not covered by this warranty.

      The warranty certificate, along with proof of purchase, MUST be presented to the BLUEFLOW service, when making a claim for replacement. The original exhaust product must also be returned and exchanged for a new exhaust product of the same part number.
