Stainless Steel O2 Eliminator Downpipe

This integrated O2 housing downpipe, or O2 eliminator as they are often referred to, has proven to add 16whp on a stock Evo 8/9 turbo, stock air intake Lancer Evolution at factory boost levels!

It is also important to note that these gains were realized on a car that had already upgraded the catback exhaust system and replaced the catalytic converter, arguably the biggest restriction from the factory, with a test pipe! Even larger gains are inevitable on applications with further modifications or increased boost levels!


  • 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.
  • Stainless steel flex section reduces stress from engine movement increasing longevity.
  • Optimal wastegate dump location helps eliminate boost creep.
  • Fits all Evolution 8 & 9 including those equipped with an Active Center Differential (ACD).
  • Made with 2 standard bungs, will include a plug for the second bung
  • Includes all necessary gaskets and hardware including spacers to clear the factory crossmember.
  • 100% Made in the USA.
