no m8 just make a flange for the front
from this




havnt got any piccys of the flange on the front , if ya want to have a look ill go into the garage and take ya some piccys , but its just a bolt on flange to the normal 60mm or what ever inlet size you want to use ,

and yes a remap IS ESSENTIAL believe me , when kenny did mine we mapped it restricted 1st and all was sorted , removed the restrictor and it fookin detted like a bastard , fook all fuel at the top end m8 , as thats what the restictor does , just chokes the top end boost , had to put multipliers in at the top for 403's !! goes mint tho !
