BD Diesel Up Pipes Kit for Ford 7.3L PowerStroke 1999.5-2003 Up Pipe Replacement

The BD Diesel Up-Pipes Kit for Ford 7.3L PowerStroke (1999.5–2003) is a purpose-built upgrade that replaces the aging factory up-pipes from the exhaust manifold to the turbo. Designed for heavy use and towing, this kit minimizes the leak-prone weak points that rob turbo drive pressure and drive up exhaust gas temperatures, helping your PowerStroke maintain confident power and cooler operation when you need it most.

Why this upgrade matters

Leaky up-pipes are a common performance limiter on V8 Turbo diesel engines. By delivering a robust, leak-resistant path from manifold to turbo, the BD kit preserves boost pressure, reduces heat bleed, and enhances throttle response across the RPM range. The result is steadier turbo spool, improved towing capability, and more predictable power delivery on steep grades or during late-load pulls.

Key features that drive real-world benefits

• Replaces vulnerable factory up-pipes with a rugged stainless design to minimize pressure loss and the associated high exhaust gas temperatures.
• Crush donuts are upgraded to stainless steel gaskets, delivering a longer seal life and consistent performance under demanding conditions.
• Larger diameter 304 stainless Up-Pipes with internally shielded expansion bellows maximize heat transfer to the turbo, boosting boost response and throttle progression.
• Internally shielded expansion bellows minimize restriction and protect piping from burn-out, especially under high-boost scenarios.
• 2-inch 304L stainless tubing and a 304L stainless turbo Y-adapter resist heat loss and corrosion, delivering longer service life than aluminized steel or lower-grade stainless options.
• An integrated upgrade that combines high-silicon ductile iron Y-adapter with stainless components for a dependable, efficient exhaust flow from manifold to turbine.

Real-world advantages

• : By maintaining pressure and reducing heat bleed, the turbo spins more reliably during heavy towing or climbing grades.
• : Stainless gaskets and durable pipework are designed to outlast the original hardware in demanding conditions, lowering the risk of manifolds-to-turbo leaks.
• : The upgraded path is a robust foundation for additional engine or transmission work, reducing the need for frequent service calls related to exhaust leaks.

Compatibility, installation, and care

Replaces the factory up-pipes on Ford 7.3L PowerStroke engines from 1999.5 through 2003 (F-250, F-350, Excursion, E-350). This kit is not for sale in licensed California vehicles and is not compatible with early 1999 PowerStrokes built on 03/21/99 or earlier. Surface rust is not eligible for warranty coverage.

Installation time is typically around 3 hours for a professional installer, with engine/transmission work often performed concurrently. The kit carries a warranty of 12 months or 24,000 miles, whichever comes first, and meets EPA reasonable basis requirements (EMS:2) for emissions compliance.

What you get with the BD Diesel Up-Pipes Kit

• Two larger-diameter 304L stainless Up-Pipes
• High-silicon ductile iron Y-adapter
• 304L stainless steel hardware and mounting components
• Stainless steel gaskets for durable, long-lasting seals
• Hardware kit for secure installation

Why choose BD Diesel

BD Diesel brings a legacy of durability and performance for diesel enthusiasts who demand reliable upgrades. This Up-Pipes Kit is engineered to provide a longer-lasting, higher-performance exhaust path that aligns with the PowerStroke’s demanding operating conditions—whether you’re towing heavy loads, negotiating steep grades, or restoring drivetrain reliability after other repairs.

Practical tips for best results

• Plan to perform other concurrent engine or transmission service work to maximize the value of the upgrade, since the kit is designed to pair with broader reliability improvements.
• Verify vehicle eligibility against the compatibility notes before purchase to avoid issues with CA-registered vehicles or late-1999 PowerStrokes.
• Follow the included installation guidelines and consider professional installation to ensure a precise, leak-free seal and optimal heat management.
