I pulled the dog box off today for a few minutes. There seems to be 2 pc of rubber hose connecting the air filter housing to the turbo, with the baffle thingy in the middle. If removing the baffle won't hurt anything, I think I could remove every thing from it to the air filter housing, and replace it with a filter setup like you're working on, and then fab my own "t" and have the long part extend all the way to where the baffle housing was removed, directly into the last rubber tube before the turbo. It looks like it would have to be shaped to fit, but a few feed of 4" muffler pipe should do the trick, along with a cut off disk in the grinder, and a mig welder.... I can make it one piece, "t" and all...
