Overview

RennTech's downpipe for the 2021 AMG GT Black Series 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 to bolt to the factory AMG GT Black Series exhaust, with hardware and clamps, for gains of up to 12 hp and 12 lb-ft. Sold for closed-course motorsport or export only, not for US public roads.
