    MAP Stainless Steel CompGate40 O2 Eliminator Downpipe for Evo X - Modern Automotive Performance

    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.
    • Integrated Wideband O2 Bung
    • 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.
