Valvetronic - BMW M3 / M4 Equal Length Valved Sport Exhaust System (F80 / F82 / F83)

Material:Grade 5 Titanium

Sound Developments.

At Valvetronic Designs, we are chasing perfection and we believe this, our equal-length exhaust setup, is the sound solution for F8x owners. Traditionally equal length exhaust configuartion lowers the aggressive nature of the S55 engine. With this new design we have spent countless hours testing to ensure the raw aggressive sound is present through all rev ranges to give that emotion, but the equal length configuration allows for the sound to be very pleasurable rather than just loud. Owners coming from other non-equal length setups will not feel short-changed in regards to this setup's volume.

At last, we are bringing the valved capability to the E46 M3 platform. Our 8-month development process has led us to a design that gives an unparalleled sound experience. S54 has never sounded so good. Constructed of brushed T304 stainless steel or available in titanium, this valved section 3 connects to any section 2 and replaces the heavy suitcase muffler. When the Valve is open the true E46 M3 S54 sound experience is unlocked with an incredibly raw engaging sound throughout the entire rev range. When the valves are closed the car is returned to a stock-like sound level for that stealthy experience.
