This design disrupts exhaust pulse velocity and creates excessive back pressure at higher RPM, choking scavenging efficiency right as the \u003cstrong\u003eH22A1\u003c\/strong\u003e engages its high-lift VTEC cam profile. In addition, repeated thermal cycling often leads to hairline fractures in aged OEM cast iron manifolds, compromising exhaust velocity and causing pre-converter leaks.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eFabricated from mandrel-bent T-304 stainless steel tubing, this 4-2-1 tri-Y header optimizes pulse scavenging across the mid-to-high RPM range. Smooth 2.00-inch primaries transition into paired secondaries to maintain optimal gas velocity, allowing the \u003cstrong\u003eH22A1\u003c\/strong\u003e DOHC VTEC engine to evacuate spent combustion gases rapidly. CNC-machined thick mounting flanges resist warping under sustained thermal loads, while the integrated front pipe flex section absorbs engine pitch to protect downstream exhaust components. Precision-placed pre- and post-catalytic O2 sensor bungs allow plug-and-play sensor integration without custom fabrication.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Exhaust Header (4-2-1 Tri-Y Design)\u003c\/li\u003e\n  \u003cli\u003e1 Front Pipe with Integrated Flex Section\u003c\/li\u003e\n  \u003cli\u003e3 Exhaust Gaskets\u003c\/li\u003e\n  \u003cli\u003eMounting Bolts and Nuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1993-1996 Honda Prelude\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eH22A1 \/ BB1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e190 hp \/ 158 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1993-1996 Honda Prelude VTEC 2.2L H22A1 DOHC 4-Cylinder\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the BB1 Prelude?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1993-1996 Honda Prelude equipped with the \u003cstrong\u003eH22A1\u003c\/strong\u003e engine. \u003cstrong\u003eThis header does not fit non-VTEC models equipped with the 2.2L F22 or 2.3L H23 engines.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eAre new hardware and installation gaskets provided with this system?\u003c\/h4\u003e\n\u003cp\u003eYes, the package includes complete mounting hardware along with three direct-fit gaskets to ensure a leak-free seal upon installation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Honda Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eMaximize your DOHC VTEC powertrain with free-flowing exhaust architecture that sharpens throttle response, improves high-RPM power delivery, and delivers an aggressive, resonant exhaust note.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67896011751672,"sku":"DS-E16Z6W95Q","price":170.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/stainless-steel-exhaust-header-for-honda-prelude-1993-1996-2-2l-1.jpg?v=1793290870","url":"https:\/\/performancechiptuning.com\/de\/products\/stainless-steel-exhaust-header-for-honda-prelude-1993-1996-2-2l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
