These high flow turbo exhaust adapters replace the factory adapters on 2011 – 2017 (including Gen 2) F150s, F150 Raptors, Expeditions and Navigators that have the 3.5L Ecoboost engine. These larger adapters will maximize flow, greatly reduce exhaust backpressure and help to lower Exhaust Gas Temperatures. The outlet is 2.3125″ ID compared to the stock outlet which is 2.0625″ ID.

SPD dyno’d a completely stock 2016 F150 3.5 Ecoboost and got 338HP and 386LBS of torque at the wheels. After these adapters were bolted on, with no other modifications, the truck made 359HP and 403LBS of torque. That’s an increase of 21HP and 17LBS of torque at the wheels!


SPD also tested a 2017 Raptor and measured an increase of 24HP and 43ft-lbs.

These high flow adapters will directly bolt on to the factory turbo and any other “drop in” style turbos that will accept the stock adapter. These will work with the factory downpipe or any aftermarket downpipe that bolts up to the factory adapters.

Come as a pair (2 adapters) and a stud socket is also included.

An install kit is required when installing the adapters, and is also available on our site here:
