Subjected to decades of thermal cycling, the stock casting frequently develops stress fractures along the runner seams and collector junctions, causing persistent exhaust leaks, warped mounting flanges, and degraded volumetric efficiency that chokes high-RPM engine breathing.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a direct bolt-on replacement (MPN \u003cstrong\u003eSPT-EHD1465\u003c\/strong\u003e), this header uses polished stainless steel with smooth, mandrel-bent primary tubes to eliminate turbulence and optimize laminar exhaust flow. Thick, precision-machined flanges resist warping under sustained exhaust gas temperatures, ensuring a dependable seal against the cylinder head. The integrated collector maximizes inertia scavenging to pull spent exhaust pulses cleanly out of each combustion chamber without cross-runner reversion.\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; margin-bottom: 20px;\"\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;\"\u003e1990-1999 Toyota Celica\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;\"\u003e\n\u003cstrong\u003e5S-FE\u003c\/strong\u003e \/ \u003cstrong\u003eST184\u003c\/strong\u003e, \u003cstrong\u003eST204\u003c\/strong\u003e\n\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;\"\u003e130-135 hp \/ 145 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;\"\u003eSPT-EHD1465 \/ Stock Manifold\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1990-1993 Toyota Celica GT \/ GT-S (2.2L 5S-FE, ST184)\u003c\/li\u003e\n  \u003cli\u003e1994-1999 Toyota Celica GT (2.2L 5S-FE, ST204)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the ST184 and ST204 Celica?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1990-1999 Toyota Celica equipped with the \u003cstrong\u003e5S-FE\u003c\/strong\u003e 2.2L naturally aspirated engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs an ECU tune required after installing this header?\u003c\/strong\u003e\u003cbr\u003e No tune is strictly required for safe operation, though an aftermarket tune can extract maximum horsepower and torque from the improved scavenging dynamics.\u003c\/p\u003e\n\n\u003ch3\u003eThe Toyota Performance Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to enhance the classic naturally aspirated JDM driving dynamic, this stainless tubular header delivers a more responsive throttle pedal, a deeper exhaust tone, and lasting corrosion resistance over cracked factory cast manifolds.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50606681850104,"sku":"DS-EK7ZB682I","price":254.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/exhaust-header-for-toyota-celica-1990-1999-2-2l-1.jpg?v=1790090679","url":"https:\/\/performancechiptuning.com\/fr\/products\/exhaust-header-for-toyota-celica-1990-1999-2-2l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
