Description
The Endura Motorsport Downpipe is specially designed for the Mercedes A45 / A45S / CLA45 AMG W177 / C118 and delivers maximum performance improvement by removing the main catalytic converter. With a generous diameter of 3.5 inches (89 mm) This downpipe ensures optimal gas flow, resulting in an aggressive AMG sound and an impressive power gain up to +28 hp on a Stage 1 setup.
The downpipe is made of T304 stainless steel and provided with handmade TIG welding for maximum strength and a perfect fit. Thanks to the thermal insulation heat dissipation is reduced by as much as 50%, further increasing engine performance and reliability.
