Huge Power Potential and a Ferocious Roar for your 2015-2018 F150 EcoBoost
If you're going for big power gains on your 2015-2018 F150 2.7L EcoBoost build, then one of the most effective ways to do it is by swapping out the factory downpipes and their restrictive catalytic converters for something more efficient. aFe's MACH Force XP 3" catted downpipes for the 2.7L EcoBoost F150s gives your truck's twin turbochargers much more room to exhale, reducing back pressure and restrictions to enable your F150 to make big power gains, especially after their required custom tuning. aFe's downpipes are larger and more efficient than stock and come with less restrictive catalytic converters to boos exhaust outflow for big gains. The downpipes bolt-on right in place of stock, making them a fairly painless way to push your 2015-2018 2.7L EcoBoost F150 to the limits of its performance envelope.
3" Diameter Mandrel-Bent Tubing with High-Flow Cats
The MACH Force XP downpipes were designed and built from the ground up to improve the performance of your F150's entire exhaust system and get your truck the horsepower and torque output it deserves. The downpipes are made from 3" diameter tubing that's all mandrel-bent to minimize restrictions and back pressure. The downpipes meet at a specialized collector assembly that's perfectly angled to ensure excellent outflow patterns. This version of the downpipe features a pair of high-flow catalytic converters that help quiet up drone and rasp while allowing more exhaust flow than stock. The entire kit is made out of 409 stainless steel that resists corrosion in most environments. The downpipes come with a full set of hardware and installation instructions.
Custom Tuning Required:
these downpipes will require custom tuning. 5-Star no longer deactivates oxygen sensors, and your truck may throw a check engine light.
