Evo 4-6 A/C hose upgrade
This is an upgrade for those of you with an Evo 4-6 that want to get rid of the discharge hose that sits against the heat shield. All you require is the discharge hose from an evo 8-9, a drill bit, and a vice.
You may have to bend the hose a bit to get it where you want, this is perfectly fine. Instead of looping the hose up and to the right as it was from factory, it drops down instead.
Make sure you properly depressurize your A/C system before attempting to remove the factory hose!
