Overview

RennTech's downpipe for the 2014-2020 CLA 45 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. That is a gain of 10 hp and 10 lb-ft.

Key details

This stainless downpipe is for M133 45 AMG engines in the A 45, CLA 45 and GLA 45. Its 200-cell catalyst flows much more freely than the factory unit while still cleaning the exhaust well enough to keep the check-engine light off.

Features

  • Free-flowing downpipe design
  • 200-cell sport catalytic converter
  • Less back pressure behind the turbo
