Engineered specifically for the 4.0T twin-turbo V8, these downpipes eliminate factory exhaust restrictions to dramatically improve turbo efficiency, throttle response, and overall power output.
By replacing the restrictive factory catalytic converters with a straight-through, free-flow design, these downpipes allow the engine to breathe freely—resulting in noticeable gains in horsepower and torque, along with a louder, more aggressive exhaust tone.
