Introduction
The 6.4L Powerstroke Downpipe-Back Exhaust is a full 4-inch T409 stainless steel exhaust replacement designed for 2008-2010 Ford F-250 and F-350 Super Duty trucks. Starting at the downpipe exit and running back to the tailpipe, the larger 4-inch diameter reduces exhaust backpressure compared to the restrictive factory system, improving exhaust flow, lowering exhaust gas temperatures, and supporting better turbo spool on both the high-pressure and low-pressure turbos of the 6.4L's twin-turbo setup.

Key Features & Build Details
- 4' T409 Stainless Steel Construction - Corrosion-resistant, high-strength tubing built for durability and long-term performance in demanding conditions.
- Downpipe-Back System - Replaces the entire exhaust from the downpipe exit to the tailpipe, eliminating factory restrictions across the full exhaust path.
- No-Muffler Design - Straight-through flow reduces backpressure while delivering a louder, more aggressive exhaust tone suited to performance builds.
- Complete Hardware Kit - Includes all clamps and hangers needed for a secure, rattle-free installation without sourcing additional components.
- Twin-Turbo Compatible - Designed around the 6.4L's high-pressure and low-pressure turbo configuration to support faster spool and improved exhaust scavenging.
Performance Benefits
- Reduced Exhaust Backpressure - The 4-inch diameter free-flowing design significantly outflows the restrictive factory exhaust, easing load on both turbos.
- Lower Exhaust Gas Temperatures - Improved flow helps evacuate heat more efficiently, reducing thermal stress on engine and turbo components under heavy load.
- Faster Turbo Spool - Less restriction in the exhaust path supports quicker boost buildup from the twin-turbo system, improving throttle response.
- Enhanced Engine Efficiency - Better exhaust evacuation reduces pumping losses, supporting more consistent performance during towing or competition use.

This exhaust system is not compatible with Cab & Chassis configurations — use the exhaust system designed specifically for those body styles. Intended strictly for off-road or competition vehicles and not approved for street use.

Great customer service, fast shipping
6.4 EGR delete stopped coolant leaks. Truck runs quieter and pulls harder. Took a day but runs like new.
worked great, complete kit, runs fine.
Worked fine no issues
What a difference!
Nice complete kit. Performed as needed. It actually keeps the oil cleaner. Like it very much.
Great kit. What a difference !
"The EGR Valve & Cooler Delete Kit is an absolute game-changer for my 2009 F250. The fuel economy improvement is noticeable, and the high flow elbow genuinely boosts the performance. Installation was a breeze, thanks to the included hardware and gaskets."
"Impressed by the quality of the kit. The high-flow elbow seems well made and polished. While I haven't noticed a significant increase in fuel economy, the engine does seem to run smoother."
"A worthwhile purchase for my 2010 F450. The increased engine longevity is an excellent perk, and the kit was relatively easy to install. The entire EGR system removal has given my truck a new lease of life."
This 6.4 delete kit saved my Powerstroke. Exhaust temps dropped. Sounds mean with the straight pipe.
This 6.4 Powerstroke EGR delete saved my engine. No more coolant mixing and turbo spools faster.
