The kit was designed to work with the oem set up, mountune set up, atp hot side charge pipe or our hot side charge pipe. Anything that is a "full" hard pipe is just a bad idea. The engine has wayyyy to much movement for a full hard pipe. Every bump every gear change the engine is moving a decent amount to that hard pipe is pulling hard on what ever it is attached to. Turbo, intercooler, intake etc... Our systems need the long rubber or silicone hoses for the movement and flex. There have been soooo many reports of people breaking there hard pipes at the mount because of this already. Just not a good ideal.
