Milltek Large-Bore Downpipe with Hi-Flow Sports Cat & GPF-OPF Bypass for W177 Mercedes-AMG A45 / S and C118 CLA45 / S

Milltek Sport’s Cast Downpipes improve gas flow and heat management, enhancing both efficiency and performance. The HJS High-Flow Sports Catalyst is distinguished as the highest quality and best-performing aftermarket option available. Unlike standard OEM catalysts, which typically have 500-600 cells, Milltek Sport’s high-flow catalyst reduces this to 200 cells, allowing for freer gas flow and superior performance.
