What i done is i got a pal to fabricate it and cut some of the attachment off, and welded the HKS flange onto the pipe, although he did say some of the welding did react to the aluminium piping, but did a good job thou, hav`nt got my intercooler fitted yet, but got my HKS fitting done, so probably would be a good idea if you know someone that can do a bit of fabrication
