RVNG 4” True Single Valved Quad-Tip Exhaust – F97/F98 X3M & X4M

The RVNG-designed 4” True Single Valved Exhaust System for the F97 X3M and F98 X4M was engineered to deliver maximum flow, an aggressive exhaust note, and a clean true-single layout from front to back.

Built from mandrel-bent 304 stainless steel, the system transitions the factory dual exhaust layout into a large 4-inch true single configuration designed to reduce unnecessary restriction while maintaining strong exhaust velocity and flow for high-horsepower S58 applications.

One of the biggest features of our 4” system is the included swappable resonated and non-resonated midsection. Every exhaust comes with both versions at no additional cost, allowing customers to change the sound of the system whenever they want.

The center section is secured using two V-band connections, meaning you can quickly swap between the resonated and non-resonated configurations without cutting, welding, or modifying the exhaust.

Run the non-resonated section when you want the loudest, most aggressive version of the system, or install the resonated section for a smoother and more refined exhaust note with reduced cabin resonance and drone.

The valved rear section gives you even more control over the sound. With the valve open, exhaust gases flow through the unrestricted performance path for maximum sound and flow. Close the valve and the system redirects exhaust through the quieter side of the muffler for a more refined driving experience.

Finished with RVNG’s signature quad perforated exhaust tips, the system combines aggressive styling, sound, and performance in one complete package.
