Exhausts, cats & accessories 45 much so that in recent years, the prices of all three have reached record highs, making them targets for criminal activity. From theft of a catalytic converter itself to the illegal trade in low-grade or counterfeit replacements, the soaring prices have fuelled a black-market economy that undermines the legitimate work by manufacturers and distributors. Despite often looking convincing, counterfeit parts are far from genuine. Marketed as equivalents or budget alternatives, the truth is that behind the attractive pricing often lies poorquality materials, weak construction, and minimal, if any, testing. In some extreme cases, these devices contain little to no precious metal coating, drastically reducing their ability to convert harmful emissions. Others use incorrect cell densities or substrate materials, leading to premature failure and higher costs. The problem currently being faced is made worse by online marketplaces and small importers, where quality assurance is minimal, and traceability is near impossible. As a result, garages and distributors can unknowingly purchase and fit substandard products that fail to meet basic emissions standards. At BM Catalysts, every product undergoes rigorous testing to ensure full compliance with UK and EU regulations. This commitment to quality and performance helps protect not only air quality, but also the reputation of the aftermarket industry as a whole. Spotting the fakes: Research and vigilance Detecting counterfeit parts is not always easy. Many counterfeiters have become increasingly sophisticated in replicating legitimate branding and packaging, a problem seen far beyond the automotive industry. That is why BM Catalysts continues to invest in research, testing and industry collaboration to help identify fake parts and protect the supply chain. Every genuine BM Catalysts part features a unique serial number, which enables full traceability from production through to installation. This serial number provides complete visibility across the manufacturing process, giving distributors and technicians the confidence that the part they’re fitting is authentic, tested and reliable. This also allows product details to be quickly verified, performance feedback to be tracked, and the highest standards of quality assurance to be maintained. Garages and technicians are also encouraged to purchase only from reputable and trusted distributors, while being cautious of unusually low prices and vague product descriptions. Especially where serial numbers or typeapproval markings are missing. The importance of type approval The root cause of the counterfeit issue comes from whether an emissions control device can guarantee compliance, performance and safety and only type-approved parts can do so. Type approval means that a part has undergone rigorous laboratory testing and meets the standards required by law for emissions, durability and fitment. In contrast, non-approved parts may not have been tested at all, leaving vehicles vulnerable to higher emissions or complete failure in some instances. All BM Catalysts products are designed from OE and manufactured and tested under the same conditions to meet or exceed the requirements. This ensures that every part performs as intended, fits perfectly and complies with the latest emissions legislation. For garages, technicians and motorists, fitting a type-approved parts means confidence in quality, compliance and long-term reliability. Protecting the future of the aftermarket Counterfeit parts are a threat to the credibility of the entire automotive aftermarket; as counterfeit operations become more sophisticated, the challenge of stopping them will only intensify. By choosing emissions control devices that are genuine and typeapproved, while remaining vigilant to the signs of counterfeiting, the industry can help safeguard both customers and the environment. BM Catalysts is committed to driving awareness, supporting research and upholding the highest standard of product integrity. Because counterfeits cost more than money, they cost credibility, compliance and clean air. bmcats.com/news Counterfeiters have become increasingly sophisticated
