Because the H2 forces air into the cylinders at up to 2.4× atmospheric pressure, the engine achieves an estimated volumetric efficiency of 120–140 % under peak boost, far beyond what a naturally aspirated engine can manage. That extra airflow means a dramatically higher exhaust velocity, especially at high rpm where the supercharger’s efficiency peaks.\u003c\/p\u003e\n\u003cp\u003eOur header starts with a precision laser-cut flange that is internally and externally TIG-welded for a perfectly smooth transitions into the primary tubes. The optimally tuned primary tubes hug the back of the engine to help reduce heat transfer into the cargo area. The primary tubes feed into our unique 4-1 cyclonic collector, that helps to manage the high exhaust flow rates associated with a supercharged engine.\u003c\/p\u003e\n\u003cp\u003eSpherical composite graphite gaskets create the perfect seal at every mating surface while maintaining uninterrupted exhaust flow. The system is secured with heavy-duty exhaust springs that allow the exhaust to flex and move naturally during extreme abuse or rough terrain. This prevents the cracks and leaks that rigid connections commonly develop.\u003c\/p\u003e\n\u003cp\u003eThe header connects to our large-radius, free-flowing 2.5\" mid pipes. Choose the standard mid pipe or upgrade to our famous RPM E-Valve setup for versatile on-demand sound control at the flip of a switch, quiet and refined when you want it, aggressive when you need it. Both mid pipe options include dual O2 bungs: one for the factory sensor and one conveniently located M18 bung (the most common size for wideband sensors during dyno tuning and data logging). An O2 bung plug is included.\u003c\/p\u003e\n\u003cp\u003eOur RPM Q-Series chambered muffler is our quietest option, engineered specifically for the H2’s unique high flow exhaust characteristics. It uses mechanical chambers and precise internal geometry for excellent sound control while flowing freely enough to support well into the 300+ HP range, ensuring it never becomes a restriction on stock or heavily boosted builds. \u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"auto\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eProven Performance\u003c\/strong\u003e: +23 HP (≈+11 % gain) over the stock baseline when paired with an RPM Carbon Intake and 91-octane tune.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimally Tuned Header Design\u003c\/strong\u003e – tuned primary tube lengths and diameter deliver maximum exhaust flow through our cyclonic 4-1 collector, perfectly matched to the centrifugal supercharger’s elevated exhaust mass flow and 120–140 % VE.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpherical Composite Graphite Gaskets\u003c\/strong\u003e – perfect seal without interrupting flow and eliminate metal-on-metal contact.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy-Duty Exhaust Springs\u003c\/strong\u003e – allow natural flex during hard hits or rough terrain.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge-Radius 2.5\" Mid Pipes\u003c\/strong\u003e – fully free flowing with optional RPM E-Valve for on-demand sound control.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual O2 Bungs\u003c\/strong\u003e – factory location plus M18 wideband bung (plug included).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuietest Q-Series Chambered Muffler\u003c\/strong\u003e – tailored to the H2’s supercharged flow dynamics; supports 300+ HP without restriction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable 304 Stainless Muffler Bracket\u003c\/strong\u003e – perfect centering in the rear fascia.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarbed-Head CNC Isolator Pins\u003c\/strong\u003e – lock securely into factory isolators.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpark Arrestor Ready\u003c\/strong\u003e – compatible with optional RPM spark arrestors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptional Polished or Blued Tips\u003c\/strong\u003e – for a sharper, more aggressive look.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"auto\"\u003eBuilt with premium 304 stainless steel and TIG welded throughout for maximum strength and reliability.
