Every megaphone is engineered and built to order around the specific vehicle, engine combination, exhaust system, intended operating range, and available installation space.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0in;\"\u003eMegaphone dimensions are selected according to the characteristics of the build, including the target RPM range, naturally aspirated, turbocharged, or supercharged configuration, engine combination and power level, exhaust tube diameter, exhaust system layout, available packaging space, and intended vehicle use.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0in;\"\u003eThe taper, expansion rate, outlet diameter, and overall geometry of a megaphone directly affect exhaust gas expansion and pressure-wave behavior. Because of this, ARL does not use a one-size-fits-all megaphone design. A megaphone designed for a high-RPM naturally aspirated engine should not simply be duplicated for a turbocharged or supercharged combination and expected to produce the same results.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0in;\"\u003eEach ARL megaphone is designed as part of the complete exhaust system, with the goal of maintaining maximum practical exhaust flow while targeting the desired operating characteristics of the individual build.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0in;\"\u003eDesigned in-house using CAD and application-specific calculations, tested in real-world applications, and manufactured in-house by Aronson Racing Lab.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0in;\"\u003eDesigned Around\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"MsoNormal\"\u003eTarget engine RPM range\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eNaturally aspirated applications\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eTurbocharged applications\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eSupercharged \/ blower applications\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eEngine combination and power level\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eExhaust tube diameter\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eExhaust system layout\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eAvailable installation length and surrounding clearance\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eStreet, performance, or race use\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eDesired low-, mid-, or high-RPM characteristics\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0in;\"\u003eConstruction \u0026amp; Features\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"MsoNormal\"\u003eEngineered and manufactured in-house\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eBuilt specifically for the individual application\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eHigh-grade 304 stainless steel standard\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003e321 stainless steel available for extreme-temperature and race applications\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003ePrecision TIG-welded construction\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eFully back-purged during welding\u003cspan style=\"mso-spacerun: yes;\"\u003e  \u003c\/span\u003eto protect the internal weld surface and maintain weld integrity\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eApplication-specific inlet, outlet, taper, expansion angle, and overall length\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eDesigned for maximum practical exhaust flow\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0in;\"\u003eIntended Use\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0in;\"\u003eDesigned for naturally aspirated performance and race engines, turbocharged combinations, supercharged\/blower applications, and custom exhaust systems where exhaust flow, pressure-wave behavior, packaging, and operating range are important to the overall system design.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0in;\"\u003eEvery ARL megaphone is built to order.
