Milltek Secondary Cat Back System for BMW 3 Series

The Milltek Secondary Cat Back System is a premium aftermarket upgrade designed specifically for the BMW 3 Series G80 M3 and M3 Competition S58 3.0 Turbo models (2021-2026). This system offers a unique combination of performance, aesthetics, and functionality. Engineered to replace the factory exhaust system, this kit features a Centre Resonator Bypass for enhanced sound and a JET-115 Carbon Fiber Trims to elevate the overall look of your vehicle. With its tailored design, this system is compatible with North American and ROW Non-OPF/GPF cars, ensuring a perfect fit and optimal performance.

Product Properties and Specifications

The Milltek Secondary Cat Back System is crafted with high-quality materials to deliver superior performance. It includes a durable stainless steel construction, ensuring long-lasting durability and resistance to corrosion. The Centre Resonator Bypass is designed to reduce the sound-dampening effects of the factory particulate filter, resulting in a deeper, more aggressive exhaust note. Additionally, the JET-115 Carbon Fiber Trims add a sleek, modern look to your BMW 3 Series, setting it apart from the competition. This system requires minor modifications to the OE exhaust, as indicated by the "OE Requires Cutting" note, but the included instructions ensure a straightforward installation process.

Practical Uses and Benefits

The Milltek Secondary Cat Back System is not just a cosmetic upgrade; it's a performance enhancer. By improving the exhaust flow and eliminating the restrictive factory setup, this system provides a noticeable increase in power and throttle response. Whether you're looking to enhance the driving experience or simply want to personalize your BMW 3 Series, this system is the perfect choice. It's ideal for daily drivers, track enthusiasts, and anyone seeking a sportier exhaust note. With Milltek Sport's commitment to quality and innovation, this system is a must-have for any BMW 3 Series owner looking to maximize their vehicle's performance and style.
