ATR Stainless Steel Downpipe
with external wastegate


Features of Note:
  • The stock downpipe (bottom) is obviously much smaller than the ATR downpipe (top)
  • The ATR pipe has very smooth bends, in addition to being 3" in diameter
  • The wastegate is attached to the ATR pipe
  • The smaller tube takes the output from the wastegate and routes it back into the exhaust
  • The wastegate is a generation II or later ATR wastegate
  • The stocker is designed to mate to a "doughnut" style gasket on a cast iron elbow, while the ATR has a smooth 3" mandrel bent curve with the gate mounted externally
