AMS is first in class because of our long history of durability and performance with industry leading engineering. We are extremely excited to introduce the next BIG thing in the AMS engineering and performance tradition, the AMS Performance Ford F150 3.5L EcoBoost Downpipes! Our stainless-steel downpipe upgrade is the perfect piece to increase the performance of your high-output 2015+ 3.5L EcoBoost Engine. The Ford F150s factory downpipes are extremely restrictive. Our Engineers utilized the powerful Solidworks software program to design less restrictive transitions for the hot exhaust gasses. The creation of smoother organic transitions allows exhaust gases to flow more efficiently which lets your turbos spool quicker, delivering a ton of power, faster. AMS Downpipes feature a 24.7% increase in cross sectional area at the inlet, the largest on the market. Our AMS Downpipes mounting flanges are chamfered to evenly distribute clamping force, and our downpipes feature 49 State legal catalytic converters.
