Overview

RennTech's downpipe for the 2018-2026 Aston Martin Vantage and DB11 V8 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

Built to fit the factory Aston Martin exhaust, with mounting hardware and clamps included. RennTech lists the Vantage V8 and DB11 V8 and rates the gain at up to 10 hp and 10 lb-ft. Sold for closed-course motorsport or export use only, not for US public roads.
