Yeah, well companies who sell this product advertise that this pipe would fit my evo 16g with the correct size coupler in which i bought with it. Like I said: when I tryed to install it the radiator hose got in my way, so what i simply did was move it a little bit in order to get the pipe by.2nd step: My fmic piping set-up has the stock ruber hose coming from the J-pipe to the intercooler pipe. now with that said , the intercooler rubber hose rides the radiator fan bracket and sits between the intake and fan bracket. 3rd step i did was remove that hose and install the intake. well after i removed it i tryed to fit the coupler on the turbo but for some reason it wouldnt go any further then the tip of the turbo inlet. so i took a view from underneath the car and found out that the coupler was hitting the wastgate needle( which is not a ebay wastgate). So my other option was to see if just the coupler would fit. And sure enough the coupler did fit by itself. Then i took the pipe and tryed to slide it in the coupler but when i did that it just simply expanded just enough where it hit the wastgate needle and couldnt fit. I will post pics this weekened when i get a chance to pull it off again. But i was just wondering why big DOG companies say this pipe bolts up because of its NEW DESIGN (for the 16g turbos) and what not, and it ends up being a pain in the ass and cant fit...
If anyone is running a 4inch intake on there 16g let me know how you managed to install it unless im the only UNintelligent guy here trying to fit a 4" intake on my 16g....?? thanks for your help

(below are 2 pics from my camera phone not the greatest but the first pic shows the mark on the coupler from the wastgate needle and 2nd pic is the coupler im using)
