A downpipe carries exhaust from the turbo(s); catted keeps the catalytic converter(s) in place.

why this one — cp-e's QKspl downpipe is a single part that fits both the standard 3.5L EcoBoost and the Raptor, a flexible pick if you want a cp-e-built downpipe across either engine.

heads up

Aftermarket catalytic converter downpipe. No CARB-legal statement found either way as of this research pass; verify state emissions compliance (especially CA) with counsel before listing.
