I have a new set of polished aluminum intercooler pipes for sale that fit the stock twins to a generic ebay style front mount intercooler core. This is the turbo side only. The piping routes through the fender. The piping will come with all necessary couplers and clamps to hook up the turbo side. Piping is 2 1/2 inches. The coupler that mounts the piping to the intercooler is a 2 1/2" to 3" transition. Price is $100 plus shipping. Here's a pic of the pipes. Sorry for the shitty camera phone shot.
