This bellowed exhaust up-pipe kit is designed for late 1999.5–2003 Ford Super Duty trucks with the 7.3L Powerstroke diesel engine, including compatible F-250, F-350, F-450, and F-550 applications.
Built from T304 stainless steel, this application-specific pre-turbo exhaust up-pipe assembly replaces the factory up-pipe layout with a bellowed tube design intended for the listed late-model 7.3L Powerstroke configuration.
F-250 / F-350 / F-450 / F-550 with the 7.3L Powerstroke diesel.
Pre-turbo exhaust up-pipe replacement for the listed 7.3L applications.
Bellowed exhaust-tube design for the factory up-pipe location.
This up-pipe kit is intended for the listed late 1999.5–2003 7.3L Powerstroke applications. It is not intended for Early 1999 / e99 configurations. Confirm the exact model year, engine, existing up-pipe layout, flange connections, and turbo-area configuration before ordering.
The exhaust up pipes on the 7.3L Powerstroke carry exhaust gas from the exhaust manifold area toward the turbocharger. As these trucks age, leakage around the factory up-pipe sealing area can become a common reason owners replace or upgrade the original assembly.
XKV21054 is a vehicle-specific bellowed up-pipe replacement kit for compatible late 1999.5–2003 Ford Super Duty 7.3L Powerstroke applications. The bellowed section provides flexibility through the pre-turbo exhaust path while retaining the application-specific routing required for the listed trucks.
It is not a complete turbocharger kit, turbo-back exhaust system, EBPV delete pedestal kit, compressor-wheel upgrade, intercooler pipe kit, or universal exhaust pipe.
Use the table below to confirm the main listed applications. Fitment should be verified by exact model year, 7.3L Powerstroke engine, existing up-pipe layout, flange connection, and turbo-area configuration.
| Vehicle | Year | Engine | Fitment Notes |
|---|---|---|---|
| Ford F-250 Super Duty | 1999.5–2003 | 7.3L Powerstroke Diesel | Late 1999.5–2003 configuration · Verify existing up-pipe and turbo-side connection before ordering |
| Ford F-350 Super Duty | 1999.5–2003 | 7.3L Powerstroke Diesel | Late 1999.5–2003 configuration · Verify existing up-pipe and turbo-side connection before ordering |
| Ford F-450 Super Duty | 1999.5–2003 | 7.3L Powerstroke Diesel | Confirm exact truck configuration and existing pre-turbo exhaust layout before installation |
| Ford F-550 Super Duty | 1999.5–2003 | 7.3L Powerstroke Diesel | Confirm exact truck configuration and existing pre-turbo exhaust layout before installation |
The up-pipe assembly operates in a high-temperature area between the exhaust manifolds and turbocharger. A bellowed section allows controlled flexibility within the exhaust path as the system heats, cools, and moves during normal engine operation.
XKV21054 is specifically an up-pipe replacement product. Keeping this distinction clear is important when comparing other 7.3L Powerstroke turbo-area parts.
Compare the received components with the product photos before installation. If you need confirmation of the exact gaskets, bolts, or hardware included with the current package, contact us before ordering.
Installation is performed in a confined turbo-area location. Existing modifications, non-original turbo components, or altered exhaust connections may affect fitment and may require additional adjustment.
This product is the standalone bellowed up-pipe kit. If you are already servicing the turbo area and also want to replace or upgrade additional components, XKV Racing also offers a separate Up Pipes + EBPV Delete Pedestal + Compressor Wheel bundle.
Choose the standalone up-pipe kit when your purchase intent is specifically the pre-turbo exhaust up pipes. Choose the larger upgrade bundle only when the additional pedestal and compressor-wheel components are required.

The up-pipe carries exhaust gases from the exhaust manifold to the turbocharger. Because it sits upstream of the turbo, this section plays a role in how exhaust energy is delivered to the turbine.
On turbocharged vehicles, the condition and design of the up-pipe can influence how smoothly exhaust flow reaches the turbo, especially under sustained load or higher exhaust temperatures.
Engineered to meet packaging, cost, and emissions requirements
May include design elements that prioritize durability and compliance
Designed with exhaust flow and heat management in mind
Built to handle higher exhaust temperatures
Often used as part of a turbo-related exhaust system setup
