Kooks/arh Offroad H-pipe

[Legacy 5.0]

I've been looking at headers and pretty much settled on kooks or arh the actual price of the header is not TOO far off others I had heard about, but the offroad hpipe is 500+ itself meanwhile adding a hpipe in a kit with say mbrp only adds around 200. is kooks that much different? and is there another brand hpipe that can fit to the headers or just a cheaper alternative.
