aFe Power has answered the call for F-150 Ecoboost owners who wish to upgrade their factory downpipe (AKA y-pipe). aFe is offering multiple options of the downpipe for the Ford EcoBoost's performance needs. Choose either the high-flowing y-pipe with 2 metallic spun, (49-state legal and Canada legal) 300 CPSI, high-flow catalytic converters, which keeps the system a true bolt-on and go solution or an off-road performance y-pipe with no catalytic converters for maximum performance. The system with catalytic converters will give you up to 16 horsepower and 18 lbs. x ft. of torque as verified on aFe's in-house dyno. Available in aluminized or 409 stainless steel tubing, both options come mandrel-bent using the latest manufacturing technologies.

For maximum flow and performance the unique y-pipes incorporate a 3" to a 3-1/2" true merge pipe collector that connects directly to the factory exhaust location. The true merge-collector is a mitered design, which reduces turbulences for better flow and performance over the tradition form-type collectors. aFe also includes all necessary hardware for a hassle-free installation.
