These high flow downpipes replace the restrictive downpipes and factory cats on 2017+ F-150 Raptors with the 3.5 HO EcoBoost motor. These larger diameter pipes will maximize flow, greatly reduce exhaust backpressure and help to lower Exhaust Gas Temperatures.
These downpipes are a direct bolt on replacement for your factory downpipes and work perfectly with the SPD Turbo Adapters.
