BMW M4 G82 G83 Delete Pipes

QuickSilver's OPF and Secondary Catalyst delete pipes transform the BMW M4 G82/G83 into an acoustic masterpiece. Engineered to pair seamlessly with the Sound Architect™ system, these mandrel-bent components remove factory restrictions while maintaining full emissions compliance through intelligent pre-programmed connectors.

The system defeats the factory's arbitrary valve closure programming that restricts sound below 30mph, giving drivers complete control via the downloadable Sound Architect app. With valves permanently open, enjoy stunning crackles and pops on overrun; with valves closed, experience refined civility for everyday driving.

Key Features:

• 76mm mandrel-bent tubing removes restrictive OPF filters and 600 CPSI secondary catalysts
• Pre-programmed terminator connectors prevent error codes without ECU remapping
• Sound Architect™ app control opens or closes valves permanently in any driving mode
• Internal resonated H-pipe design delivers punchy tone without intrusive cabin frequencies
• 101mm carbon fibre tailpipes provide premium aesthetic finish
• Fully reversible to stock configuration without ECU trace

Includes:

• OPF and Secondary Catalyst delete pipes
• Pre-programmed terminator connectors with OPF cancellation lead kit
• Sound Architect™ electronic module with Bluetooth connectivity
• Android and iOS compatible app

Sharper throttle response, stunning definition, and complete sonic control. Your M4, your rules.
