If your at stock cubes then you can do 1 3/4 but if you plan on going higher on the cubes than stock then you may want to get the 1 7/8. But either brand is great I would say which ever one is cheaper that's what I would go with.

arh design is basically the same as kooks....ive "heard" some dudes from kooks went on to start arh....but thats just what i "heard".... anyways the biggest difference betwixt the two would be the merge in the y. but they are both great merges. flip a coin or look for a deal imo....

Even if you're at stock cubes get the 1 7/8. I've seen better results over 1 3/4 with the 1 7/8 and that was stock cubes. Do a search and you should find it.

The two are nearly identical, but I like the collector of the AR Headers over the kooks.

The ARH Y merge is way better unless Kooks has revised their design.

If you are using a y the ARH y fits better and has a better merge IMO. About two years ago Kooks redesigned their collector and added a velocity spike so they are now about identical to ARH in this area...
