Mercedes-AMG A45 & CLA45 Downpipe Guide — M133 M139 Catless vs 200-Cell, Power Gains & Sound (2026)
Why Upgrade the Downpipe on an AMG A45 / CLA45?The Mercedes-AMG A45 and CLA45 use either the M133 (W176/C117, 2013–2019) or M139 (W177/C118, 2019+) turbocharged four-cylinder engine — the most powerful production four-cylinders ever built. The factory downpipe includes a restrictive catalytic converter close-coupled to the turbo. Upgrading to a high-flow downpipe is the most effective bolt-on for reducing turbo lag, increasing peak power, and adding exhaust character to these compact AMG models.Catless vs 200-Cell — Comparison Table Type HP Gain (with Stage 2) Torque Gain Emissions Sound Best For Catless (race) +50–80 WHP +50–70 lb-ft Off-road / track only...

The factory downpipes include two primary catalytic converters that restrict exhaust gas flow from the turbos. Upgrading to high-flow downpipes is the most impactful bolt-on for reducing turbo lag, boosting peak power, and giving the G-Class a deeper, more commanding exhaust note.Catless vs 200-Cell — Comparison Table Type HP Gain (with Stage 2) Torque Gain Emissions Sound Best For Catless (race) +80–120 WHP +90–130 lb-ft Off-road only Very...
