Paired with a chambered Flowsound muffler utilizing a high-flow 3.0-inch single inlet and dual 2.5-inch outlets, the system balances acoustic resonance while promoting laminar flow. The dual tailpipes exit straight back under the rear bumper parallel to the frame rails, cleanly clearing factory receiver hitches and full-size OEM spare tire mounts across all standard wheelbase layouts.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Flowsound 2-chamber muffler (single 3\" inlet, dual 2.5\" outlets)\u003c\/li\u003e\n  \u003cli\u003e2 Aluminized mandrel-bent two-piece 2.5\" tail pipes (slip-together design)\u003c\/li\u003e\n  \u003cli\u003e8 Muffler clamps\u003c\/li\u003e\n  \u003cli\u003e1 Larger exhaust clamp\u003c\/li\u003e\n  \u003cli\u003e4 Rubber-insulated hangers\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;\"\u003e1987-1996 Ford F-250\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;\"\u003e4.9L, 5.8L, 7.5L Gasoline \/ OBS Platform\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;\"\u003e145-245 hp \/ 265-400 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\u003e1987-1996 Ford F-250 4.9L Inline-6 (Gasoline, factory single-inlet muffler only)\u003c\/li\u003e\n  \u003cli\u003e1987-1996 Ford F-250 5.8L V8 (Gasoline, factory single-inlet muffler only)\u003c\/li\u003e\n  \u003cli\u003e1987-1996 Ford F-250 7.5L V8 (Gasoline, factory single-inlet muffler only)\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 OBS F-250?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a fit for the 1987-1996 Ford F-250 equipped with the \u003cstrong\u003e4.9L\u003c\/strong\u003e, \u003cstrong\u003e5.8L\u003c\/strong\u003e, or \u003cstrong\u003e7.5L\u003c\/strong\u003e gasoline engines with single-inlet factory mufflers. \u003cstrong\u003eIt does not fit diesel models (6.9L\/7.3L IDI or Power Stroke), dual-inlet factory exhaust layouts, or trucks with aftermarket relocated fuel tanks.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eIs this exhaust kit a direct bolt-on installation?\u003c\/h4\u003e\n\u003cp\u003eNo, this is not a direct bolt-on system; professional installation is recommended as intermediate tube fabrication may be required depending on cab configuration, wheelbase length, and aftermarket suspension clearance.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle severe-duty commercial hauling and off-road trail vibrations, this exhaust setup replaces brittle factory tubing with corrosion-resistant aluminized steel engineered to handle sustained heavy towing loads without failing.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67562630873336,"sku":"DS-EL9JIFY9H","price":229.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/exhaust-kit-for-ford-f-250-1987-1996-4-9l-5-8l-7-5l-1.jpg?v=1790987590","url":"https:\/\/performancechiptuning.com\/products\/exhaust-kit-for-ford-f-250-1987-1996-4-9l-5-8l-7-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
