The aFe 49-43090-B Large Bore-HD system uses five-inch mandrel-bent 409 stainless tubing, an OE-style flange and factory-style hangers behind the retained diesel particulate filter. The selected six-inch stainless tip has a black finish and intercooling vents. The manufacturer specifies hand MIG welding.
The current exact manufacturer page, observed application table and visually printed guide identify 2017–2026 F-250 Super Duty and F-350 Super Duty 6.7L Power Stroke diesel pickups. The complete exact selected EuroPartShop table supports the twelve named rows below; Limited is supported only for 2018–2024. Every row remains subject to the manufacturer’s factory fifth-wheel-hitch exclusion and actual cab/bed configuration. No F-450/F-550, cab-and-chassis, gas-engine or additional named trim mapping is inferred from broader secondary lists.

It is the five-inch 409 stainless Large Bore-HD DPF-back system with a six-inch black tip for the documented Ford diesel pickups, subject to the factory fifth-wheel-hitch exclusion.
Will it fit a truck with the factory fifth-wheel hitch?No. The exact current manufacturer page explicitly excludes the factory fifth-wheel hitch. A broad model-year or named-trim match does not override that equipment restriction.
Does this system remove the particulate filter?No. It fits behind the retained factory particulate filter. No deletion, tuning or emissions-equipment removal is authorized or required by this listing.
Which cab configurations need trimming?The guide rounds regular long-bed wheelbase to 142 inches: trim approximately four inches from its flange adaptor and omit the extension. Extended short bed uses the flange adaptor without an extension. Extended long bed uses an extension trimmed to 19 inches; crew short bed uses one trimmed to 15 inches. Crew long bed uses the full extension without cutting. Confirm the actual vehicle and measure before cutting.
Are two or three band clamps included?The formal diagram lists two five-inch bands, while the disassembled product photo shows three. That source discrepancy remains open; confirm the actual supplied packing list rather than assuming a third clamp is guaranteed.
Are the original gasket and hangers reused?Yes. Protect and reuse the original gasket and rubber isolation mounts. The #53 hanger clamp faces the front of the truck in the selected guide.
What does the guide say about sensors and tightening?It says to tighten the NOx sensor bung after aligning the exhaust and tightening from the front flange toward the rear bands. It supplies no numeric torque or sensor-transfer/wiring procedure. Check for leaks and re-tighten clamps if necessary after 50–100 miles.
Is Limited covered for every model year or a power gain guaranteed?No. The exact selected named table supports Limited only for 2018–2024. No measured selected power, EGT, MPG or drone result was verified; those outcomes are not guaranteed.
