This isn't a full cat-back - SPD doesn't sell a complete cat-back for the 2017-2020 Raptor. This is a muffler/resonator upgrade meant to pair with the factory system or an SPD downpipe.

why this one — SPD has no standalone cat-back for this Raptor generation, only muffler/resonator upgrade pieces - this is one of four such options they offer, so make sure it's actually what you're after before buying.
