Is your truck equiped with the EGR system. EGR intake horns are quite restrictive. If it is equiped with egr or was at one point, I would swap in the non EGR horn. If you already have a non-egr horn, then I wouldn't worry about it. You aren't going to accomplish a lot and your money is better spent elsewhere. If you are building a truck for all out power and money is not an issue then that is something to consider. However, I wouldn't really worry too much about it at this point.
