Valvetronic Designs V2 Valved Sport Exhaust System for E9x BMW M3

Valvetronic Designs V2 Valved Sport Exhaust System for E9x BMW M3

Version 2 of Valvetronic Designs’ E9X M3 Valved Exhaust System advances reliability and sound refinement, setting a new benchmark for the platform. Returning to vacuum-actuated valves chosen for their proven durability and consistent operation this iteration features enhanced acoustic tuning for a purer, more engaging driving experience. Crafted from premium brushed T304 stainless steel and fully mandrel-bent for maximum flow, the system offers true dual-personality performance: subdued cruising with the valves closed or the unfiltered S65 V8 soundtrack with the valves open. In keeping with Valvetronic Designs’ mission to make premium valved systems attainable, this package delivers flagship quality without compromise. For even greater performance and tone, it pairs seamlessly with Valvetronic Designs’ high-performance X-pipe mid-section, offered in both free-flow and catted configurations.

Sound & Control

• Valvetronic Designs calibrates a dual-character exhaust: with valves closed, it preserves factory-like refinement for urban driving and long-distance cruising; with valves open, it releases an aggressive, motorsport-inspired V8 tone with sharper throttle response. The system offers flexible configuration—run the rear section alone or opt for the complete setup with the matching mid-pipe.

Mid-Pipe Options

• Valvetronic Designs offers two X-pipe options to tailor performance and tone: the Free-Flow X-Pipe delivers an aggressive note and maximum horsepower gains with a large post-tunnel X-merge for optimal scavenging, while the Catted X-Pipe integrates 200-cell Euro 6 catalytic converters to improve emissions compliance without compromising flow. Upstream, a four-resonator front section smooths pulse noise right from the engine, refining the soundtrack without muting character.

Why It Works

• Valvetronic Designs specifies vacuum-actuated valves for proven reliability and rapid response, enabling seamless, on-demand sound control. High-flow, mandrel-bent tubing enhances throttle response and overall power delivery. Staying true to the brand’s mission, the system delivers premium valved performance without the excessive “M tax.”
