Description
BMW X4 G02 LCI (ROW/USA) - Secondary Catalyst Bypass
Product Overview
This Milltek Sport secondary catalyst bypass is designed for the BMW X4 G02 LCI (ROW/USA) in the Secondary Catalyst Bypass configuration. It replaces the secondary catalyst section with freer-flowing pipework to reduce restriction and increase exhaust character while integrating with the exhaust configuration stated in the product title.
Product Details
As the GPF/OPF almost acts as a secondary catalyst; we have provided the option to remove this component; similar to a Decat system. This bypass deletes the GPF/OPF; removing it from the exhaust system to better improve performance. All our performance exhaust systems are designed with you in mind; and we cater to an ever-expanding range of vehicles. We believe in continuous evolution; and our research & development team work throughout the year to deliver the most in demand solutions to all your performance exhaust requirements. All of our products are made in the UK and distributed to more than 90 countries worldwide; making Milltek Sport one of the most accessible performance aftermarket brands on the market.
