i used an r32 bumper and used a allard fmic which i plumbed in myself. it was all a bit hit and miss but the end product is pretty good i think. total cost of fmic/hoses/pipe ect was around ?300. and im getting good power and torque, and even after a long hard drive last summer the fmic was still cool to the touch.have a look at my pic and you will see it looks ok, just click on the link.
