Take your 2003-2007 Ford 6.0L PowerStroke to the next level with the SWAG PERFORMANCE High-Flow Exhaust Manifold Kit — engineered to outperform stock manifolds and built for long life under high heat and heavy load. Designed as a direct bolt-in replacement, this manifold kit addresses common PowerStroke issues like warping, cracking, and leaks while providing measurable performance gains.
Built for Performance:
SWAG manifolds feature an optimized internal design that increases exhaust flow and improves cylinder evacuation. By reducing backpressure and retaining exhaust gas temperatures, this kit enhances turbocharger efficiency, delivering quicker spool-up and stronger throttle response across the RPM range.
Heavy-Duty Construction:
Manufactured from thick, heat-resistant materials with a high-temperature coating, SWAG PERFORMANCE manifolds resist corrosion and thermal distortion better than OEM castings. Like other premium aftermarket units, this kit helps prevent burn-through and common manifold failures, giving you durability you can depend on.
Race-Ready & Service-Friendly:
Pre-drilled ports make it easy to add pyrometer probes for precise EGT monitoring, just like higher-end performance manifolds. Whether you’re building a daily driver or a tuned work truck, this kit supports upgrades and diagnostics without extra fabrication.
Complete Kit — Install with Confidence:
Everything you need is included — driver and passenger side manifolds plus gaskets and hardware. The direct replacement fit makes installation straightforward with existing factory mounting points.
Key Features & Benefits
Performance Benefits
-
Improved Exhaust Flow
Optimized runner design lowers backpressure and promotes better turbo efficiency and throttle response relative to stock manifolds. -
Reduced Exhaust Gas Temps (EGTs)
More efficient gas evacuation helps reduce EGTs under load — promoting cooler, more stable engine operation.
