Overview

RennTech's downpipe for the 2019-2026 G 63 AMG replaces the restrictive factory part with a free-flowing design and a 200-cell sport catalytic converter, cutting back pressure behind the turbo for quicker spool and more power.

Key details

Made for the factory G 63 exhaust on 2019+ W463A cars, hardware and clamps included, with gains of up to 10 hp and 10 lb-ft. For closed-course motorsport or export use only; not for US public roads.
