Mitsubishi Evolution 4-6 O2 Eliminator Downpipe


  • Full 3'' design reduces exhaust restrictions and is the only true 3'' option available!
  • Made from 304 stainless steel for superior corrosion resistance and enhanced appearance.
  • Mandrel bent tubing throughout optimizes exhaust flow.
  • SS flex section reduces stress from engine movement increasing longevity.
  • Integrated Wideband O2 Bung
  • Optimal waste gate dump location helps eliminate boost creep.
  • Includes all necessary gaskets and hardware including spacers to clear the factory crossmember.


  • External wastegate dump: This is the absolute best option in regards to performance as the waste gate gases never reenter the exhaust system. Please note that under full boost the exhaust will be considerably louder. This option is intended for off road use only as venting exhaust gases prior to a catalytic converter is illegal in most states.
  • Recirculated wastegate dump: Standard O2 housing configurations recirculate the waste gate gases just inches away from the turbine outlet resulting in turbulence and decreased performance. Our unit recirculates the waste gate gases as far away from the turbine outlet as possible to provide you with the best possible performance without the additional noise from the external dump.
  • Test Pipe / High Flow Catalyst: Further increase exhaust flow by adding either a test pipe or high flow catalyst to your purchase. Please note this is a separate component.

CNC 3D Countoured Flange

We offer this product with CNC 3D contoured flange, the standard flange has been performing flawlessly for the majority of our customers since this product's inception in 2009, but there have been a handful of customers that experienced boost creep when trying to run lower boost levels (less than 25psi) with upgraded turbochargers.
