TRD dual exhaust and cold air intake

Sorry if there is already a thread out there on this but I couldn’t find one. I have a 2018 TRD off-road double cab. I tow a 25’ travel trailer during summer months. I am trying to find out if installing the TRD dual exhaust and an S&B cold air intake is really going to give the truck a boost. If I do this mod I do want to stick with the original TRD dual exhaust. I like the idea of a more aggressive tone to the truck however that takes second place to the mods actually providing a noticeable increase in hp and torque. I assume I would have to have it re-tuned if I make the changes. Also, would changing only one of these provide any benefit?
