Improves Power and Flow without throwing CELs

The stock downpipes and factory catalytic converters are the most restrictive components of your F150’s 3.5L EcoBoost V6, and if you want your aggressive F150 EcoBoost build to make some big power, you’ll need SPD’s 3″ Catted Downpipes. SPD’s Catted Downpipes offer a big improvement in exhaust outflow and efficiency that can see your F150 make awesome levels of power after the right custom tuning. SPD’s downpipes come standard with a ceramic finish that gives them superior corrosion resistance than other aluminized downpipes. SPD’s catted downpipes even use catalytic converters that don’t throw a CEL and help you keep your F150 emissions-compliant and street-legal in most areas. SPD’s catted downpipes install right into place of your F150’s factory downpipes without cutting or trimming, saving you time and hassles.

3″ Diameter Aluminized Steel with Ceramic-Coat Finish

SPD’s Catted Downpipes were carefully designed to improve your F150’s performance, all while giving you long-term reliability and emissions compliance. SPD’s catted downpipes are built around 3″ diameter, mandrel-bent tubing that allows for much more efficient exhaust flow with less backpressure than the stock downpipes. SPD’s catted downpipes feature catalytic converters designed to avoid CELs, but that still offer improved exhaust flow over the stock cats, but still help prevent CELs and keep your F150 street-legal in non-CARB states. The downpipes are made entirely out of aluminized steel that then receives a gray VHT high-temp ceramic coating to further protect them from corrosion and provide some extra heat insulation. The coating can be re-applied if damaged. SPD’s downpipes install in place of your F150’s factory downpipes without permanent modifications and come with all their necessary hardware.
