Bolt‑on 201SS bellowed up‑pipes with gaskets and hardware for 1999.5–2003 7.3L Powerstroke, replacing the factory crush‑doughnut style pipes that commonly crack and leak. Improves sealing, lowers EGTs, and helps your turbo spool quicker while maintaining OEM‑style fitment.
Upgrade the weak, leak‑prone factory up‑pipes on your 7.3L with a bellowed up-pipe kit designed to restore lost power, reduce exhaust leaks, and improve turbo response on late‑1999.5–2003 Ford Powerstroke trucks. Perfect for stock or mildly upgraded builds that need reliability and clean boost control.
Eliminates common factory up‑pipe exhaust leaks and soot build‑up at the collector.
Bellowed flex sections reduce stress and cracking from heat cycles and vibration.
201 Stainless steel construction for better corrosion resistance and longer service life.
Restores lost power, drive pressure, and turbo spool on high‑mileage 7.3 trucks.
Direct bolt‑on for 1999.5–2003 7.3L F‑250/F‑350/F‑450/F‑550 with stock‑location turbo.
Includes gaskets (and hardware where applicable) for a complete install.
From the factory, 7.3L Powerstroke up‑pipes use crush‑doughnut connections that eventually warp, crack, and leak, costing you boost, power, and fuel efficiency. This stainless bellowed up‑pipe kit replaces those failure‑prone pipes with a high‑flow, flex‑joint design that maintains a tight seal through thousands of heat cycles.
The bellowed sections allow movement without stressing the flanges, greatly reducing the chance of future leaks at the manifolds and turbo collector. That means more consistent drive pressure, lower EGTs, and more reliable turbo performance whether you tow, daily drive, or run a mild tune.
Designed as an OEM‑style upgrade, this kit bolts in place of the stock up‑pipes on late‑1999.5–2003 7.3L F‑250, F‑350, F‑450, and F‑550 trucks with the intercooler, feeding the stock‑location turbocharger. It includes new gaskets and typically the key hardware needed so you are not reusing tired, soot‑caked seals during the job.
This NorCal Diesel Performance Bellowed Up-Pipe kit is backed by a limited 1‑year manufacturer warranty against defects in materials and workmanship. Normal wear, misuse, improper installation, or modified applications are usually excluded by such warranties.
Ticking or puffing exhaust sound from behind the engine near the turbo.
Visible soot streaks on the back of the engine or up‑pipes.
Slower turbo spool, loss of boost, or lazy throttle response.
Elevated EGTs under load and reduced towing performance.
Exhaust smell in the cab, especially at idle or with the windows down.
Q: What trucks does this fit?
A: It is intended for 1999.5–2003 7.3L Powerstroke F‑250, F‑350, F‑450, and F‑550 with the intercooler and stock‑location turbo; it does not fit 1994–1997 or early‑1999 (e99) trucks.
Q: Do I need any special tuning for these up‑pipes?
A: No tuning is required; they are an OEM‑style replacement that simply seals better and flows more consistently than worn factory pipes.
Q: Can I use this with an aftermarket turbo?
A: As long as the turbo uses a stock‑style pedestal and collector location, these up‑pipes generally work; non‑stock mounting or T4/T6 kits may require different piping.
Q: What is the typical install time?
A: Expect around 4 hours for an experienced DIYer or professional with proper tools and lift access, since the turbo and related components must usually be removed.
