Designed as a direct replacement for the restrictive factory downpipes, this upgrade improves exhaust flow, enhances turbo response, and delivers noticeable gains in performance while maintaining catalytic converters that support emissions compliance.\u003c\/p\u003e\u003cp\u003eThe factory downpipes on the EcoBoost platform are a major restriction in the exhaust system. By replacing them with larger-diameter mandrel-bent tubing and super high-flow catalytic converters, exhaust gases exit the turbochargers more efficiently—helping the turbos spool faster and reducing exhaust backpressure.\u003c\/p\u003e\u003cp\u003ePerformance Benefits\u003c\/p\u003e\u003cp\u003eOur catted downpipes are engineered to unlock the true potential of the EcoBoost platform while retaining catalytic functionality.\u003c\/p\u003e\u003ch4\u003eKey improvements include\u003c\/h4\u003e\u003cp\u003eImproved turbo spool \u0026amp;amp; throttle response – Reduced backpressure allows the twin turbos to reach boost quicker.\u003c\/p\u003e\u003cp\u003eIncreased horsepower and torque potential – More efficient exhaust flow supports higher power levels, especially when paired with tuning and supporting mods.\u003c\/p\u003e\u003cp\u003eEnhanced turbo sound and deeper exhaust tone – A more aggressive sound without excessive drone.\u003c\/p\u003e\u003cp\u003ePotential fuel efficiency improvements under light throttle conditions due to reduced restriction.\u003c\/p\u003e\u003cp\u003eWhether you’re building a street truck, tow rig, or weekend performance F-150, these downpipes provide the ideal balance of power, durability, and emissions-conscious design.\u003c\/p\u003e\u003cp\u003eEPA-Compliant Ultra High-Flow Catalytic Converters\u003c\/p\u003e\u003cp\u003eThis variant includes a pair of 5\" ultra high flow GESI catalytic converters that will NOT produce a CEL!\u003c\/p\u003e\u003cp\u003eThe GESI Ultra High Output Catalytic Converter features full 304 stainless steel construction, including the substrate. GESI Catalytic Converters are EPA registered and compliant in 49 states and fully OBD2 compliant, perfect for use on 1996 and newer vehicles. Active proprietary precious metal loading technology ensures greatly reduced emissions, eliminating most \"Check Engine Lights\". These high flow catalytic converters outperform stock converters and provide a reliable solution to the most common catalytic converter problems.\u003c\/p\u003e\u003cp\u003eThe GESI Catalytic Converters are rated for engines putting out up to 1,000 horsepower while maintaining a high flow capacity.
