At MAP our goal is to offer the highest quality products available at a price that anyone can afford. This integrated O2 housing downpipe, or O2 eliminator as they are often referred to, does just that by removing some of the largest restrictions in the factory exhaust system for significant horsepower gains throughout the power band! It also features a Turbosmart CompGate40 external wastegate (sold separately) for improved boost control when the factory internal wastegate configuration isn't able to do the job (larger stock frame turbochargers at high boost levels).

To preserve spool characteristics we recommend running the factory internal wastegate in conjunction with this product, please contact us for additional information.

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.
  • Includes stainless steel turbo outlet gasket (not shown).
  • 100% Made in the USA.

Turbosmart wastegate not included by default, please choose below from the drop-down if you want one included. Please note, the dump tube you receive will be "clearanced" which cannot be seen in the picture as fitment of this product relies on a very small window.


Advanced Ceramic Coating

This black ceramic coating increases exhaust velocity and reduces under hood temperatures for improved performance and appearance.

Second O2 Bung

Add an additional O2 sensor bung for your wideband sensor, etc.

Flange Options

We offer this product with your choice of turbine outlet flange, standard or 3D contoured. 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. In general if you are swapping out your existing o2 housing for this upgraded unit and plan to run 25+ psi you shouldn't have an issue with the standard flange. If, however, you just performed a significant upgrade (complete engine build, turbocharger upgrade, etc.) and would prefer to begin the tuning process below 25psi or if you ultimately plan to run less than 25psi we recommend the 3D contoured option to ensure you have complete boost control.
