What Universal X-pipe kits are good?

im in no rush to put it on, just in a rush to order it since im going to the border to pick it up next friday so i want to order now to make sure its there when i get there...what would be the benefits of buying the small x and doing my own piping around it? I feel that if i do the small x im going to have to pay the shop more to bend up and supply tubing...what do you guys think? im leaning towards the summit one since its cheaper too (unless i go with the small dynomax x)
