The OEM midpipe features two secondary catalytic converters and large resonators that restrict airflow and dull the exhaust tone. The MAD Resonated H-Pipe replaces those with a higher-flowing setup that eliminates the secondary flow restrictions and uses compact, carefully tuned resonators to refine the exhaust character.\u003c\/p\u003e\n\u003cp\u003eThe result is a noticeable increase in volume and tone without introducing excessive drone or harshness. It’s the ideal solution for drivers who want a deeper, more pronounced exhaust note while maintaining a smooth, refined sound throughout the RPM range.\u003c\/p\u003e\n\u003cul class=\"ak-ul\"\u003e\n\u003cli\u003e\n\u003cp\u003eFactory-style dual midpipe H-pipe design\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIncreased exhaust flow with clean, sporty tone\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDual smaller resonators help reduce unwanted frequencies\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDirect bolt-on fitment to OEM or aftermarket components\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eConstructed from high-grade stainless steel for durability\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNOTE: Downpipe gasket is not included.
