FITMENT
- 2020-2024 Ford Powerstroke F-250 / F-350 / F-450 Super Duty Diesel Pickup Truck
- Note: This is a 4" downpipe. It connects the turbocharger outlet to the mid-section exhaust.
DESCRIPTION
Product Overview
-
The factory downpipe on 2020–2024 Ford 6.7L Powerstroke trucks is a major bottleneck—its crushed sections and tight bends trap intense heat and slow down turbo spool.
- The 4" Performance Turbo Downpipe unlocks maximum airflow directly at the turbo outlet. Built from mandrel-bent 4-inch T409 stainless steel, it replaces restrictive OEM tubing with a smooth, high-flow pathway that sharply drops EGTs, reduces heat soak, and restores crisp throttle response under load.
Key Features
- Premium Mandrel-Bent Material: Crafted from 4-inch T409 stainless steel to withstand extreme EGTs and harsh road conditions without cracking.
- High-Flow Turbo Downpipe: Replaces the restrictive, pinched factory downpipe to maximize exhaust velocity straight off the turbocharger.
- Faster Turbo Spool & Response: Eliminates exhaust turbulence at the turbo outlet, enabling quicker spool-up times, sharper throttle response, and improved horsepower.
- Drastically Lower EGTs: Accelerates heat dissipation right at the hot side of the turbo, helping protect your engine during heavy towing or performance tuning.
FAQ
Q: Will this 4" downpipe connect to my stock exhaust system or a delete pipe?
A: Yes. It is engineered with direct bolt-on flanges that connect seamlessly to the factory exhaust system, as well as aftermarket DPF delete pipes or full downpipe-back exhaust systems.
Q: Do I need a custom tuner to install just the downpipe?
A: If you are retaining the stock factory DPF/emissions system behind the downpipe, a tuner is generally not required. However, to get the full performance benefits and lower EGTs, pairing this downpipe with matching delete pipe/tuning is recommended for race applications.
Q: Is installing a downpipe difficult on a 2020+ 6.7L Ford?
A: Downpipe replacement is more tight-space intensive than cat-back piping due to the tight clearance between the engine firewall and transmission. Professional installation or using appropriate shop lifts and long extensions is recommended.
Q: How does this downpipe help lower EGTs?
A: The factory downpipe has restrictive flattened sections that bottle up hot exhaust gases right after they leave the turbine wheel. The smooth 4" mandrel bends allow hot gases to expand and evacuate instantly, preventing heat soak inside the turbo.
