Catalytic Converter for BMW X6 (2011-2014) 3.0L

Direct-Fit Catalytic Converter for 2011-2014 BMW X6 (E71)

What it Does: The Direct-Fit Catalytic Converter replaces a clogged or fractured factory unit behind the turbocharger on the 2011-2014 BMW X6 xDrive35i to restore exhaust flow, clear P0420/P0430 codes, and meet EPA emissions standards.

The Stock BMW X6 Exhaust Substrate Problem

On the E71 chassis with the N55 3.0L single-turbo inline-six, extreme exhaust temperatures directly behind the turbo outlet degrade the factory ceramic substrate over time. As the honeycomb fractures or loses washcoat efficiency, engines suffer elevated backpressure, metallic rattling, sluggish turbo spool, and recurring catalyst-efficiency check engine codes.

The Direct-Fit Catalytic Solution

Built to OE specifications for 18407645241 and 18307599198, this converter pairs a rust-resistant stainless steel shell with a precious-metal ceramic honeycomb substrate for efficient HC, CO, and NOx conversion. Factory-style inlet and outlet connections, support brackets, and dual O2 sensor bungs ensure bolt-on installation with zero cutting or welding.
