Being an lml, you’re talking about a full delete. Be sure of your local laws. Federally, deleting any emissions is illegal. If you still are interested, I believe a big name company sells a full high flow kit. Which includes intake, hot and cold pipes, down pipe, and y bridge. Not sure why you’re stuck on doing both up pipes, unless you’re wanting to go with bigger ones which would net almost no gain on a mostly stock truck. The factory ones will be much better quality than the cheap eBay ones. And still be cheaper and much easier. Only ones I would 100% recommend would be profab, which are not cheap.
If doing all this, you should also do a PCV reroute.

This kit will give you everything you want and then some, with options for up pipe and pcv reroute as well. You need to be sure of your DP design. Some years are v band some are 3 bolt. Not as familiar with an lml but believe it may be the exhaust itsel, so v band should work if doing exhaust too. But don’t quote me on this.
