Milltek Secondary Cat Back System with Resonator Bypass

Introducing the Milltek Secondary Cat Back System, a cutting-edge exhaust upgrade designed specifically for the BMW 4 Series G82 M4 & M4 Competition S58 3.0 Turbo (2021-2026). This system is tailored for North American and ROW Non-OPF/GPF cars, offering a superior sound and aesthetic enhancement. The core feature of this system is the Centre Resonator Bypass, which significantly improves the exhaust note, providing a deeper, more aggressive sound. The GT-115 Polished Trims add a sleek, premium finish to your vehicle, making it stand out from the crowd.

Product Properties and Specifications

The Milltek Secondary Cat Back System is crafted with precision and quality in mind. It is designed to be a direct fitment, requiring the OE system to be cut for installation. This ensures a seamless integration with your vehicle's existing exhaust setup. The system is made from high-quality stainless steel, offering durability and corrosion resistance. It includes a Centre Resonator Bypass, which effectively compensates for the sound-reducing qualities of the OE particulate filter, resulting in a richer, more distinctive exhaust tone. The GT-115 Polished Trims are crafted from aluminum, providing a polished, sophisticated look that complements the modern design of the BMW 4 Series.

Practical Uses and Benefits

The Milltek Secondary Cat Back System is not just a visual upgrade; it also offers practical benefits. The improved exhaust note enhances the driving experience, making your BMW 4 Series feel more dynamic and responsive. The system is designed to increase airflow, which can lead to better engine performance and fuel efficiency. Whether you're driving through the city or on the open road, this exhaust system ensures a smooth, enjoyable ride. The premium finish of the GT-115 Polished Trims adds to the overall appeal of your vehicle, making it a standout choice for BMW enthusiasts seeking both performance and aesthetics. With Milltek Sport, you're choosing a brand that is committed to delivering the highest quality performance exhaust solutions worldwide.
