I hope this helps anyone that is looking to get a kit an skeptical of the company. Parts came in 4 days. if you choose the race pipe style it is not meant to get rid of the last muffler so you will have to get a pipe from an exhaust shop to complete it. cost me 50 bucks. on the supplied hoses just purchase 5-6 feet of hose that away you have plenty of room for a clean install with no kinks (reuse the stock quick connects for the firewall). you will also want to get 5 feet of 1/4" fuel line hose for the turbo overflow line going to the nipple on the main coolant reservoir. This will allow you to get rid of the hard line section bolted to the top of the Y bridge for a clean install. The can bus plugs will work but they are not directly plug and play. The driver side frame well plug has a guide ridge in the can bus plug that you will have to use a razor blade to cut off to allow it to fit into the plug on the vehicles harness properly. The can bus plug with the latch on the driverside frame rail going to def harness you will have to shift the latch over the stops to allow it to swing and latch against the def harness plug, also watch dark iron diesels youtube video to show you how to unlock one of the pins that has to be shifted over when you get the plug. lastly the can bus plug going into the harness in the engine bay went in with no issues and worked properly. I would buy this kit again it is very affordable and works but you will just have to take a few extra steps that arent shown on any installation videos.
