Description

The CTS Turbo High-Flow Cat Set is engineered to significantly improve exhaust flow for Mercedes-Benz vehicles equipped with the M276 3.0L Twin-turbo engine. Crafted from durable stainless steel, this cat set directly replaces the stock catalytic converters, offering an enhanced performance pathway for your exhaust system. This high-flow cat set is specifically designed to be compatible with a range of Mercedes-Benz models featuring the M276 engine, including the C43 AMG, C400, C450 AMG, E43 AMG, E400, E450, and GLC 43 AMG. Fitment details typically include model years from 2014 through 2021 for C-Class and E-Class variants, with specific attention paid to the W205 and W213 chassis. Installation is intended to be a direct bolt-on procedure, integrating seamlessly with the factory exhaust system without requiring extensive modifications. By reducing exhaust restriction, these high-flow cats help unleash the full potential of your M276 engine, contributing to improved performance.
