ImageShack.usyou can actually buy a kit off these guys with a load of pipes included with the IC, you end up with loads more than u need. if its a regular 20VT like used in this estatee car (not a S3 one like mine in the black golf) you can use the rear metal pipe from the original set up that goes to the intercooler (small L bend pipe) but have it pointing the opposite way to how it is when in a audi A3 or MK4 golf (dont have pics with me to show which pipe i mean)
