The Valvetronic Designs Valved Exhaust System for the BMW F87 M2 unlocks the full potential of the N55 engine, delivering maximum sound when you want it and refined quietness when you don’t. Built from premium T304 stainless steel, the system connects to any downpipe and runs a 3-inch primary section before splitting into dual 2.5-inch mandrel-bent pipes, exiting through a set of premium quad tips.
This unique split design accelerates exhaust gas flow for improved performance and a more engaging tone compared to traditional single-pipe systems. Vacuum-actuated valves provide rapid operation and proven long-term reliability, all controlled by a standalone module that allows valve control in any driving mode.
Optimized Dual-Pipe Design: Splitting into two 2.5" pipes after the downpipe improves scavenging and enhances exhaust tone.
Vacuum Valve System: Reliable and responsive, with standalone control for operation at any time.
Improved Flow & Sound: Flows more efficiently and sounds richer than OEM and many aftermarket options.
Valves Open: Raw, aggressive tone with maximum volume and character.
Valves Closed: Refined, daily-drivable sound levels for comfort.
Standalone Controller: Operates independently of drive mode selection.
Material: Brushed T304 stainless steel for strength and corrosion resistance.
Weight Savings: 4.3 lb lighter than the factory exhaust.
Craftsmanship: Precision TIG welds and fully mandrel-bent tubing.
Tips: Beautiful sleeve-style tips designed to complement the F87 rear fascia.
