Description
Discover the ultimate automotive upgrade with the Active Autowerke M3 M4 Valved Exhaust. Our team is proud to present our signature exhaust system specifically designed for the BMW F8X series. After investing over a year in intensive research and development, we are thrilled to announce that production has commenced in-house, and we are now ready to ship these exceptional systems worldwide.
Our Valved Exhaust is engineered with cutting-edge features that elevate your driving experience to new heights. Crafted from premium 304 stainless steel, the 3.5" mandrel bent piping ensures optimal exhaust flow throughout the system. We have strategically positioned a 4" 100 cell high flow catalytic converter further towards the rear of the vehicle, mitigating any restrictions caused by exhaust velocity and effectively eliminating raw fuel smells. Additionally, this placement aids in smoothing out exhaust pulses, resulting in a richer and more resonant exhaust note.
Maintaining the driver side OEM exhaust valve, our system offers complete control over the exhaust flow. When the valve is closed, all exhaust flow is directed to a straight-through muffler, optimizing performance. On the other hand, when the valve is opened, the exhaust flow is allowed to pass straight through to the tips, enhancing the overall sound experience.
To ensure consistent performance, we have integrated a true 3.5" to 3.5" Y-Pipe at the rear muffler. This design choice guarantees that there is no diameter drop, irrespective of whether the valve is open or closed. This feature is especially crucial for vehicles running high boost levels or upgraded turbos, as it optimizes airflow efficiency and prevents any potential performance bottlenecks.
Manufactured with pride in Miami, FL, our Valved Exhaust system adheres to the highest standards of quality and craftsmanship. It has been meticulously engineered to provide a peak gain of 15whp over a stock exhaust, with substantial torque and horsepower improvements at lower RPMs. These gains are further amplified when combined with higher boost levels, making it an ideal choice for performance enthusiasts seeking an exhilarating driving experience.
Features include:
- Full 304 Stainless 3.5” mandrel bent piping from the downpipes back
- 4” 100 cell high flow catalytic converter strategically placed. The cat has been positioned further towards the rear of the vehicle where exhaust velocity is lower which prevents it from being restrictive to exhaust flow.
- The converter helps dial out any raw fuel smell and also helps smoothen out exhaust pulses for a deeper exhaust note.
- The driver side OEM exhaust valve is retained. When the valve is closed all exhaust flow is routed to a straight through muffler. When the valve is opened the exhaust flow allows to pass straight through to the tips.
- The Y-Pipe at the rear muffler is a true 3.5” to 3.5” Y, so there is no diameter drop regardless of whether or not the valve is open, this is especially important for those cars running high boost levels or upgraded turbos.
- Designed and manufactured here in Miami, FL.
- 15whp peak gain over a stock exhaust. As much as 70ft/lb and 30whp gains at lower RPMs. Gains will be amplified with higher boost levels.
