BMW 1 Series Catalytic Converter

This catalytic component reduces harmful gases by transforming them into safer emissions through chemical reactions inside a metal catalyst core. Located in the exhaust pipe system, it helps your BMW 1 Series remain compliant with pollution laws.

Pricing varies depending on the converter type, engine setup, and whether it connects to an exhaust manifold or is part of a larger filtration module like the DPF. Each product page includes fitment info and specifications.

When a mounting kit or gasket is provided, it's clearly mentioned. All installations must be handled by professionals to ensure warranty validity.
