You have stumbled upon the first of many upcoming product offerings produced by MAPerformance under the MAP brand name. Our goal is to offer the highest quality products available at a price that anyone can afford, and our very first product has done just that! This integrated O2 housing downpipe, or O2 eliminator as they are often referred to, has proven to add 16whp on a stock turbo, stock air intake 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!

Features / Benefits

  • 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.
  • Made with 2 bungs and includes a plug for the 2nd bung.
  • Optimal wastegate dump location helps eliminate boost creep.
  • Fits all Evolution 8 & 9 including those equipped with an Active Center Differential (ACD).
  • Includes all necessary gaskets and hardware including spacers to clear the factory crossmember.
  • 100% Made in the USA.

External wastegate dump

This is the absolute best option in regards to performance as the wastegate 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.

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.
