Which size headers?

[Torch54]

I’m looking at Kooks headers and they offer 1 3/4” and 1 7/8” options. Truck is stock really except for some Borla cat back exhaust. I’m wanting to add headers and a tune. I mainly drive in town and highway but I do tow a 4 seat rzr. When towing it’s usually for a couple hours or will be out of state. I don’t want to hamper any towing so I’m thinking the smaller tube but I really don’t know my best option. Just looking for opinions. Thanks everyone!

Unless you plan to do major performance mods, such as supercharging, big cam change, or anything like that, 1 3/4 will be all you need.

The larger ones will lose nothing but only provide more benefit the more power you make.
