ok heres my suggestion, the system you did looks good, and works well to get the filter in the well but the ridges in the plastic portion cause alot of turbulence which is bad for the intake, wont affect it too much but all the same...essential speed has mandrel bend pipes in 2.5 and 3" sizes for sale, their pretty much just elbows but they are mandrel bent and may work to do the same thing you havem you could always get a piece of aluminum pipe from somewhere like home depot or a shop and have them bend it for cheap.
Now that I think about it it is alot of work to just get rid of the ridges...lol. NIce job
