Description
Upgrade the exhaust performance and sound characteristics of your BMW M3 or M4 S58 with the MAD Resonated Single Midpipe Titanium, engineered for the G80 M3, G82 M4, and G83 M4 models. This premium exhaust upgrade is designed to improve exhaust flow, reduce weight, and deliver a more refined yet aggressive exhaust note without introducing excessive drone or harsh rasp.
Constructed from high-quality titanium, this midpipe significantly reduces weight compared to the factory system while enhancing both sound quality and overall exhaust efficiency.
Performance and Sound Enhancement
The MAD single midpipe system is designed to replace restrictive factory components and optimize exhaust gas flow for a more responsive and engaging driving experience.
Key features include:
• Improved exhaust flow for enhanced performance characteristics
• Deletion of secondary catalytic converters and resonators for a freer-flowing setup
• Retention of primary catalytic converters in the downpipes to avoid CEL issues
• Noticeably more aggressive exhaust tone compared to stock
Resonated Design for Refined Sound
This system features an integrated resonator designed to balance sound output while eliminating unwanted rasp and harsh frequencies.
Benefits of the resonated design include:
• Cleaner and smoother exhaust tone
• Reduced rasp at higher RPM
• Controlled exhaust volume suitable for daily use
• Improved sound quality when paired with aftermarket downpipes
The resonator ensures the exhaust note remains aggressive and engaging without becoming overly loud or uncomfortable for everyday driving.
Single Midpipe Configuration
The conversion to a single midpipe layout improves exhaust gas scavenging and contributes to a deeper, more unified exhaust tone.
Advantages include:
• Deeper midrange exhaust character
• Cleaner high-RPM sound profile
• Reduced high-frequency rasp
• Simplified exhaust flow path for improved efficiency
Lightweight Titanium Construction
Manufactured from premium titanium, this midpipe delivers substantial weight savings compared to the factory system.
• Total system weight (including brace and clamps): approximately 16 lbs
• Improved power-to-weight ratio
• Enhanced corrosion resistance compared to steel systems
• Motorsport-grade material durability
Important Installation Information
• Downpipe gasket is not included
• Two gaskets (Part #18308053348) are required for installation
• Professional installation is strongly recommended
