The OEM cast design suffers from unequal runner lengths, rough internal casting flashes, and a restrictive collector that induces severe exhaust turbulence. At higher RPMs, particularly when VTEC engages on the H22A4 engine, this bottleneck creates excessive backpressure, trapping latent heat within the cylinder head. This heat soak not only pulls timing and restricts high-end horsepower, but it also stifles the natural, aggressive tone of the 2.2L powerplant.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eUpgrading to this 4-1 style tubular header eliminates the factory restriction through optimized exhaust gas routing. Manufactured from durable, corrosion-resistant T-304 stainless steel, the mandrel-bent runners feature a polished finish and smooth internal walls that drastically reduce fluid friction. The 1.5\" x 1.9\" inlet ports seamlessly transition exhaust pulses into a high-velocity 2\" outlet collector, utilizing the 4-1 architecture to maximize top-end power and exhaust scavenging efficiency. Paired with a robust 3-bolt flange connection and a multi-layer metal gasket to prevent exhaust leaks, this unit ensures reliable, sustained flow dynamics during spirited driving.\u003c\/p\u003e\n  \n  \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1997-2001 Honda Prelude (Non-SH Models)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eH22A4 \/ BB6\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e195-200 hp \/ 156 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e1997 Honda Prelude 2.2L Base (Non-SH)\u003c\/li\u003e\n    \u003cli\u003e1998 Honda Prelude 2.2L Base (Non-SH)\u003c\/li\u003e\n    \u003cli\u003e1999 Honda Prelude 2.2L Base (Non-SH)\u003c\/li\u003e\n    \u003cli\u003e2000 Honda Prelude 2.2L Base (Non-SH)\u003c\/li\u003e\n    \u003cli\u003e2001 Honda Prelude 2.2L Base (Non-SH)\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Honda JDM Standard\u003c\/h3\u003e\n  \u003cp\u003eBuilt for the true Honda enthusiast, this 4-1 stainless header unlocks the distinctive VTEC crossover sound while delivering the high-RPM breathing capacity essential for any naturally aspirated H22A4 build.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48129158119672,"sku":"DS-ENHE63SZQ","price":239.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/exhaust-headers-for-honda-prelude-1997-2001-2-2l-engine-1.webp?v=1774288242","url":"https:\/\/performancechiptuning.com\/products\/exhaust-headers-for-honda-prelude-1997-2001-2-2l-engine","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
