O2 Eliminator Downpipe

At MAP the goal is to offer the highest quality products available at a price that anyone can afford. This integrated O2 housing Evo 10 downpipe, or O2 eliminator as they are often referred to, does just that by removing some of the largest restrictions in the factory Mitsubishi Evolution 10 exhaust system for significant horsepower gains throughout the power band!

Features / Benefits

  • Full 3" design reduces exhaust restrictions
  • 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
  • Made with 2 standard bungs, will include a plug for the second bung
  • Includes stainless steel turbo outlet gasket
  • 100% Made in the USA



Available with either the normal stainless steel finish or coated with an advanced ceramic coating. This black ceramic coating increases exhaust velocity and reduces under hood temperatures for improved performance and appearance.

External Dump / Recirculated

Choose between external dump configuration (shown here) or recirculated (shown at the top) for your Mitsubishi Evolution X.

CNC 3D Countoured Flange

We offer this product with CNC 3D contoured flange, the standard flange has been performing flawlessly for the majority of 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.
