MBRP S4501304 3 Inch Resonator Bypass X-Pipe for 2021+ BMW M3 G80 M4 G82

The MBRP S4501304 Resonator Bypass X-Pipe is a high-performance exhaust component designed specifically for 2021 and newer BMW M3 (G80) and M4 (G82) models with the 3.0L engine. This 3-inch X-pipe configuration deletes the factory resonators, delivering enhanced exhaust flow and a more aggressive exhaust note while maintaining excellent build quality.

Premium T304 Stainless Steel Construction:

Constructed from T304 stainless steel, this X-pipe offers superior corrosion resistance and durability compared to lower-grade materials. T304 stainless is the premium choice for exhaust components, providing exceptional longevity even in harsh environmental conditions with exposure to road salt, moisture, and extreme temperatures. The material is easy to clean and maintain, ensuring your exhaust system looks great for years to come.

Mandrel-Bent Tubing for Maximum Flow:

All tubing is precision mandrel-bent to maintain consistent 3-inch inner diameter throughout the bends, eliminating the rippling and diameter reduction common with crush-bent tubing. This engineering approach maximizes exhaust gas flow, reducing backpressure by up to 17 percent compared to the stock configuration. Improved flow means better engine breathing, which translates to increased horsepower, improved throttle response, and enhanced overall performance.

Key Features:

• Direct fit for 2021+ BMW M3 G80 and M4 G82 with 3.0L turbocharged inline-six engine
• 3-inch diameter T304 stainless steel construction
• Precision mandrel-bent tubing maintains optimal flow characteristics
• X-pipe design improves exhaust scavenging and balances flow between banks
• Resonator bypass configuration for moderate to aggressive exhaust tone
• Up to 17% increase in exhaust flow over factory system
• Compatible with both coupe and sedan body styles
• Backed by MBRP's Lifetime Warranty
• Professional installation recommended; cutting required for proper fitment

Installation Notes:

This X-pipe requires cutting of the factory exhaust system for installation. Professional installation is strongly recommended to ensure proper fitment and alignment. When installed, this component eliminates the factory resonators, which will increase exhaust volume and create a more aggressive sound character while improving performance.

Transform your BMW M3 or M4 with MBRP's performance-engineered exhaust components. This resonator bypass X-pipe delivers the perfect combination of increased performance, enhanced sound, and long-lasting quality that enthusiasts demand.
