RVNG Motorworks - S55 True 4" Valved Exhaust for BMW F80 M3 / F82 M4

From initial sketches to detailed 3D models and our final prototype, RVNG is proud to announce the release of the first-ever 4” Full True Single Midpipe Quad Tip Valved Exhaust System for the F8X S55 platform—a groundbreaking system designed to redefine sound, flow, and performance.

This isn’t just a bigger pipe—it’s a completely reimagined exhaust solution. Our 4” true single midpipe eliminates the restrictive factory dual-pipe and 3.5” crossover designs seen in other systems, allowing for smoother, uninterrupted flow from the downpipes all the way to the rear muffler section. The result? A deeper, more refined exhaust tone with less rasp, reduced backpressure, and optimal turbo efficiency—especially at higher RPMs.

The system also features an OEM-style electronic valve control, giving you the ability to switch from a quiet, neighborhood-friendly tone to a raw, aggressive sound at the press of a button. All of this flows out through a stunning quad-tip configuration, bringing both form and function to the rear of the car.

Installation is simple and efficient—our full system can be bolted in within 30 minutes, replacing the outdated 3.5” midpipe and OEM muffler with a setup that delivers both style and substance.

With this launch, RVNG is setting a new benchmark for the F8X platform. No more compromises—just a fully optimized, high-flow system designed to meet the demands of S55 owners who want the best.
