If you're looking to elevate your classic's power, sound, and overall driving experience, these headers are designed for you.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Hidden Performance Blocker:\u003c\/strong\u003e Your factory exhaust manifolds were built for compromise, not peak performance. They restrict exhaust gas flow, stifling your engine's horsepower and torque potential, and muting that iconic V8 growl. It's like running a marathon with a hand over your mouth.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Engineering Solution:\u003c\/strong\u003e Replace those restrictive cast iron manifolds with our premium exhaust headers. Engineered to optimize exhaust scavenging, these headers feature an efficient 8-2 piping design, allowing spent gases to exit the cylinders faster and more efficiently. This translates directly to improved throttle response, significant horsepower gains, and a much more assertive engine note. Crafted with CNC machine flanges and TIG\/MIG welded construction, they promise a precise fit and enduring durability. The 3-stage polish finish not only looks sharp but adds an extra layer of protection. Please note, installation instructions are not included; we recommend consulting a shop or factory manual for proper procedure.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eThe Comparative Edge\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Flow:\u003c\/strong\u003e 8-2 piping design significantly improves exhaust gas velocity and scavenging, boosting engine efficiency and power output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRobust Construction:\u003c\/strong\u003e Built with thick 7\/16\" head and 3\/8\" outlet flanges, precision CNC machining, and reinforced TIG\/MIG welding for leak-free, long-lasting performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePremium Finish:\u003c\/strong\u003e A brilliant 3-stage polish provides corrosion resistance and a show-quality appearance under the hood.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Kit:\u003c\/strong\u003e Includes two high-quality exhaust headers along with all necessary gaskets and bolts for a straightforward installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRace-Inspired Design:\u003c\/strong\u003e Features 1.75\" primary tubes and a 3.00\" outlet size, tailored for optimal performance on these classic Olds V8s.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo O2 Sensors:\u003c\/strong\u003e Designed for classic applications, these headers feature zero O2 sensor locations, perfect for period-correct builds.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 10px;\"\u003eFitment\u003c\/td\u003e\n\u003ctd style=\"padding: 10px;\"\u003e1965-1974 Oldsmobile 98, Cutlass, Delta 88, Vista Cruiser\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px;\"\u003eEngine\u003c\/td\u003e\n\u003ctd style=\"padding: 10px;\"\u003e5.7L, 6.6L, 7.5L (350\/400\/455 V8)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 10px;\"\u003ePart Number\u003c\/td\u003e\n\u003ctd style=\"padding: 10px;\"\u003e(Not specified in description)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003chr\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOldsmobile 98 (1965-1974) with 350, 400, or 455 (5.7L, 6.6L, 7.5L) V8 engines\u003c\/li\u003e\n\u003cli\u003eOldsmobile Cutlass (1965-1974) with 350, 400, or 455 (5.7L, 6.6L, 7.5L) V8 engines\u003c\/li\u003e\n\u003cli\u003eOldsmobile Delta 88 (1965-1974) with 350, 400, or 455 (5.7L, 6.6L, 7.5L) V8 engines\u003c\/li\u003e\n\u003cli\u003eOldsmobile Vista Cruiser (1965-1974) with 350, 400, or 455 (5.7L, 6.6L, 7.5L) V8 engines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Performance Promise\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eBuy with confidence.\u003c\/strong\u003e Backed by real automotive experts and fast shipping.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":47974339084536,"sku":"DS-ERTVEOPN1","price":259.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/s-l1600_a43b846b-f0a0-4364-ad6a-e56df28406d6.webp?v=1770769309","url":"https:\/\/performancechiptuning.com\/products\/exhaust-manifold-headers-for-oldsmobile-cutlass-delta-1965-1974-350-400-455","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
