i have done a similar mod to mine, i have a cone filter tho, as i have no heat shealing from the turbo, i just have a 4" pipe commin up from the front of car, (relocated horn) and have cut a whole in the arch, the filter sits ontop of the 4" pipe and slightly pops out the hole icut in arch. i have no drama with the wet, and it hissis like a beyatch when you floor it! (it has also made the wastegate chatter alot louder!
