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.
- 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.
Based on several requests for a two piece configuration we have finally released a v-band version that retains a full 3' diameter throughout! This option is only available with a recirculated wastegate dump.
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.
Warranty Information At Modern Automotive Performance we strive to offer only the highest quality products and stand behind our work. All MAP brand products will include a one year warranty from the date of purchase. In the event of a failure from a manufacturing defect we will either repair or replace the product at no cost.
