Black 6.7 Powerstroke 4" Exhaust Overview
Fitting 2011-2024 Ford 6.7 Powerstroke F250, F350 and F450 diesel trucks, our 4-inch black downpipe-back exhaust replaces the restrictive stock exhaust. It cuts backpressure to boost horsepower, torque and deliver a deep, aggressive diesel exhaust sound. Made of premium 409 stainless steel with black powder coating and titanium heat wrap, it offers excellent heat insulation and corrosion resistance. It is an ideal upgrade for tuned trucks, towing and off-road use, improving engine performance, fuel efficiency and undercarriage looks.
Black 4" Downpipe-Back Exhaust Key Features
This SPELAB 4-inch downpipe-back exhaust removes OEM exhaust bottlenecks to smooth overall exhaust flow and reduce engine backpressure. It effectively improves engine efficiency and fuel economy to lower fuel costs, maintaining stable and reliable performance for heavy towing, long hauling and off-road driving.
Black Powder Coating for Heat and Corrosion Protection
• High-Temperature Protection : Premium powder coating resists extreme exhaust heat, avoiding discoloration and thermal damage for long-lasting performance.
• Enhanced Corrosion Resistance :Shields the exhaust from road salt, moisture, mud and off-road debris for solid durability in harsh environments.
• Improved Aesthetics: Sleek matte black finish upgrades your truck’s undercarriage with a stealthy, performance-focused look.
Black Titanium Heat Wrap for Head Pipe Heat Control
• Reduced Underbody Heat Radiation: The titanium heat wrap blocks intense heat to protect hoses, wiring, fuel lines and engine parts, extending component service life.
• Extreme Temperature Endurance: Withstands over 1000°C (1832°F), perfectly suited for tuned 6.7 Powerstroke engines, heavy towing and off-road use.
• Optimized Exhaust Flow: Eliminates heat soak and backpressure to speed up exhaust flow, delivering steady power gains and smoother engine operation.
⚠ Off-Road Use Only – DPF removal is illegal for on-road vehicles in most regions. For competition/racing use only.
