These stock manifolds trap combustion heat, increase exhaust gas backpressure, and disrupt cylinder scavenging. Over decades of thermal cycling, factory iron units are also prone to developing hairline cracks, blown manifold gaskets, and warped sealing faces that cause persistent exhaust leaks.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eFabricated for the \u003cstrong\u003eSBC Gen I\u003c\/strong\u003e platform, these shorty headers feature smooth 1-5\/8-inch mandrel-bent primary tubes feeding into 2.5-inch collectors to maximize exhaust gas velocity. Thick 7\/16-inch CNC-machined cylinder head flanges and 3\/8-inch collector flanges resist thermal warpage to guarantee a leak-free seal. TIG and MIG welded stainless steel construction resists corrosion, manages underhood thermal loads, and significantly sheds weight over cast iron.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Set Stainless Steel Headers (Left \u0026amp; Right)\u003c\/li\u003e\n  \u003cli\u003e1 Set Collector Reducers\u003c\/li\u003e\n  \u003cli\u003eExhaust Manifold \u0026amp; Collector Gaskets\u003c\/li\u003e\n  \u003cli\u003eMounting Bolts \u0026amp; Washers\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;\"\u003e1975-1981 Chevrolet Camaro\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;\"\u003eSBC Gen I (4.4L, 5.0L, 5.7L) \/ F-Body\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;\"\u003e115-220 hp \/ 200-280 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\u003e1975-1981 Chevrolet Camaro (Base, LT, Berlinetta, RS, Z28) with 4.4L (267ci), 5.0L (305ci), or 5.7L (350ci) Gen I Small Block V8 (2WD only)\u003c\/li\u003e\n  \u003cli\u003eFits Gen I small block Chevy V8 displacements: 262, 265, 267, 283, 302, 305, 307, 327, 350, 400\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 F-Body Camaro?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1975-1981 Chevrolet Camaro equipped with the \u003cstrong\u003eSBC Gen I\u003c\/strong\u003e engine. \u003cstrong\u003eWill not fit Big Block Chevy engines, V6 models, or 4WD\/AWD conversions.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWill modification be required during installation?\u003c\/h4\u003e\n\u003cp\u003eAftermarket exhaust plumbing and clearance around steering shafts or linkages may require minor adjustment during installation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Muscle Caliber\u003c\/h3\u003e\n\u003cp\u003eDeliver the breathability your classic small block Chevy demands, eliminating choked exhaust runners to restore aggressive American V8 acoustic presence and dependable horsepower.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67599147827448,"sku":"DS-EOW5E9RXB","price":154.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/exhaust-header-for-chevrolet-camaro-1975-1981-4-4l-5-0l-5-7l-1.jpg?v=1791474865","url":"https:\/\/performancechiptuning.com\/de\/products\/exhaust-header-for-chevrolet-camaro-1975-1981-4-4l-5-0l-5-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
