CTS Turbo Ford Raptor EcoBoost 3.5L High-Flow Cat Downpipes

Unlock the 3.5L EcoBoost twin-turbo in your Ford Raptor with CTS Turbo high-flow cat downpipes, built to maximize exhaust flow for the biggest gains. CAD-engineered to fit perfectly in place of the restrictive factory catalytic converters, they are manufactured from T304 stainless steel, hand TIG-welded and back-purged for long-term reliability.

They also wake the truck up: a deeper, louder growl with a much more pronounced exhaust note, plus a confident punch as you bang through all 10 gears. With an aftermarket exhaust already fitted, expect even more volume. For the best flow and power, pair these with the optional turbine adapters.

The optional CEL eliminator greatly reduces the chance of a CEL for the cat-efficiency code, though it is not guaranteed to be 100% effective. Stage 2 downpipe-specific software tuning is required to avoid a check engine light.
