The factory 7.3L manifolds tend to deteriorate and crack over time, which leads to uneven clamping, broken studs, blown gaskets and power lost to exhaust leaks. KC's redesigned manifolds use thicker mounting flanges for an even seal against the cylinder head and port-matched runners that flow over 20% more than stock, reducing back pressure and improving turbo efficiency. This kit pairs the manifolds with the Odawgs Diesel Bellowed Up Pipes for the 1994.5-1998 Ford 7.3L Powerstroke, so the up-pipe joints are sealed at the same time.\u003c\/p\u003e\u003cp\u003eKC Turbos casts these manifolds from high-silicon molybdenum iron, which holds up to thermal warping and cracking far better than conventional cast iron. The up-pipe mounting face is re-engineered for better alignment and clamping under load, and the larger, fully machined sealing surface spreads heat evenly to minimize hot spots. Each pair carries an integrated EGT probe port and retains the factory EBP tube port, both with NPT plugs preinstalled, plus 16 OEM-style interference thread flange bolts that hold torque and resist backing out. The Odawgs bellowed up-pipes are made from aircraft-grade 321 stainless steel and eliminate the factory donut gasket for a tighter seal, with a bellowed design that handles heat cycles from daily driving to drag racing.\u003c\/p\u003e\u003cp\u003eInstallation reuses the factory exhaust manifold to up-pipe bolts, which are not included. A thread chaser is recommended to clean the cylinder head bolt holes before install so the new hardware reaches proper torque. The OEM-style interference thread bolts may feel like they are cross-threading as they go in; this is normal, since that interference with the head threads is what keeps them from backing out.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDirect bolt-on for 1994.5-1998 Ford 7.3L Powerstroke (OBS)\u003c\/li\u003e\n\u003cli\u003eHigh-silicon molybdenum cast iron resists warping and cracking\u003c\/li\u003e\n\u003cli\u003ePort-matched runners flow over 20% more than stock manifolds\u003c\/li\u003e\n\u003cli\u003eThicker mounting flanges seal evenly against the cylinder head\u003c\/li\u003e\n\u003cli\u003eBellowed 321 stainless up-pipes flex through heat cycles\u003c\/li\u003e\n\u003cli\u003eIntegrated EGT probe port and factory EBP port, both plugged\u003c\/li\u003e\n\u003cli\u003eEliminates the leak-prone factory up-pipe donut gaskets\u003c\/li\u003e\n\u003cli\u003e16 OEM-style interference thread bolts resist backing out\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand: KC Turbos\u003c\/li\u003e\n\u003cli\u003eProduct: Upgraded Exhaust Manifolds (Pair) and Bellowed Up-Pipes\u003c\/li\u003e\n\u003cli\u003eUp-Pipes: Odawgs Diesel Bellowed Up Pipes\u003c\/li\u003e\n\u003cli\u003eMaterial: High-silicon molybdenum (High-SiMo) cast iron\u003c\/li\u003e\n\u003cli\u003eUp-Pipe Material: Aircraft-grade 321 stainless steel\u003c\/li\u003e\n\u003cli\u003eFlow: Over 20% increase vs stock manifolds\u003c\/li\u003e\n\u003cli\u003eEGT Port: Integrated, NPT plug preinstalled\u003c\/li\u003e\n\u003cli\u003eEBP Port: Factory EBP tube port retained, NPT plug preinstalled\u003c\/li\u003e\n\u003cli\u003eGaskets: Stainless steel\u003c\/li\u003e\n\u003cli\u003eMounting Hardware: 16 OEM-style interference thread flange bolts\u003c\/li\u003e\n\u003cli\u003eManifold Bolt Torque: 45 lb-ft (61 Nm)\u003c\/li\u003e\n\u003cli\u003eEngine: Ford 7.3L Powerstroke (OBS)\u003c\/li\u003e\n\u003cli\u003eWarranty: 1 Year\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eIncluded:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e(2) KC Upgraded Exhaust Manifolds (Driver and Passenger)\u003c\/li\u003e\n\u003cli\u003e(2) Stainless Steel Exhaust Manifold Gaskets\u003c\/li\u003e\n\u003cli\u003e(16) OEM-Style Interference Thread Exhaust Flange Bolts\u003c\/li\u003e\n\u003cli\u003e(2) Preinstalled NPT Plugs (EGT and EBP Ports)\u003c\/li\u003e\n\u003cli\u003e(1) Odawgs 321 Stainless Bellowed Up-Pipe Set\u003c\/li\u003e\n\u003cli\u003e(1) Odawgs Stainless Gasket Set\u003c\/li\u003e\n\u003cli\u003e(1) Odawgs OE Install Hardware Kit\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1994.5-1998 Ford F-250 7.3L Powerstroke (OBS)\u003c\/li\u003e\n\u003cli\u003e1994.5-1998 Ford F-350 7.3L Powerstroke (OBS)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1 Year Warranty\u003c\/li\u003e\n\u003cli\u003eNot available for sale in the state of California\u003c\/li\u003e\n\u003cli\u003eNot designed to fit van applications\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KC Turbos","offers":[{"title":"Default Title","offer_id":67884144034113,"sku":"302873 | 301087","price":889.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/2504\/1821\/files\/302873_301087_kit.jpg?v=1792004678","url":"https:\/\/rudysdiesel.com\/products\/kc-turbos-upgraded-exhaust-manifolds-odawgs-bellowed-up-pipes-kit-for-1994-5-1998-ford-f-250-f-350-7-3l-powerstroke-obs","provider":"Rudy's Performance Parts","version":"1.0","type":"link"}
