Overview

The CTS Turbo High-Flow Cat is a downpipe designed to maximize exhaust flow for increased power gains on BMW N26 engines. It replaces the restrictive factory downpipe with a high-flow 200-cell catalytic converter. This part is constructed from T304 stainless steel and is hand TIG welded and back-purged for durability.
Show original supplier description
Designed with the latest CAD technology, it fits perfectly in place of your factory downpipe. Constructed from premium T304 stainless steel, this component features hand TIG welding with back-purging to ensure exceptional durability and years of reliable performance. It directly replaces the restrictive factory downpipe, incorporating a high-flow 200-cell catalytic converter to enhance exhaust gas velocity and power output. The result is an incredible, sporty exhaust sound that remains subtle during cruising and avoids any drone with the factory exhaust system. To prevent the Check Engine Light (CEL) from illuminating after installation, the use of Bootmod3 stage 2 software is strongly recommended. Please note that catalytic converters damaged by "crackle tunes" are not covered under warranty. This high-flow cat is specifically designed for the following BMW models with N26 engines: 2013-2017 BMW F2X 228i & xDrive, 2012-2016 BMW F3X 328i & xDrive, and 2014-2016 BMW F3X 428i & xDrive. It will ONLY fit N26 engines.
