Black Mamba BMW X3M / X4M F9x Decat Downpipes

All Black Mamba products undergo strict inspection and certification to ensure they comply with quality standards before being shipped. This certification complements the manufacturer’s warranty, which typically covers defects in materials or workmanship for one year on most products. Intercoolers and exhaust systems are covered by a non-transferable lifetime warranty, excluding any aesthetic defects that may develop with use. The manufacturer will determine whether products are to be replaced or repaired and may request proof or return of the items for evaluation. Please note that costs for returns and third-party services are not covered under the Black Mamba Warranty.
