Excellent quality 3” type 304L stainless steel  turbo elbows for your Evo 456 or Evo 789 (Choose from drop down) which have less restriction after the turbine housing than the stock cast elbow.

This improves turbine wheel efficiency and provides easier escape for the bypassed wastegate gasses also.

The result is lower TIP and higher held boost pressure throughout the revs and therefore more hp. No draw backs to this modification at all. An essential item for people with an Evo 9 80 series turbo looking to break the 400Hp barrier.
