O2 Eliminator Downpipe - Recirc

This integrated O2 housing Evo 10 downpipe, or O2 eliminator as they are often referred to, removes some of the largest restrictions in the factory Mitsubishi Evolution 10 exhaust system for significant horsepower gains throughout the power band!

Available with either the normal stainless steel finish or coated with our advanced ceramic coating. This black ceramic coating increases exhaust velocity and reduces underhood temperatures for improved performance and appearance. We also 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.

Ceramic Coating: Our advanced ceramic coating option helps control heat soak. The piece is coated in a thermal barrier (available in black only) that looks great and protects wires and hoses from heat. Please note the coating may need some extra "curing" to prevent flaking after installation. Please allow the part to heat up during normal driving or idling and then completely cool before putting it through it's paces.


  • 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
  • 100% Made in the USA

Please Note: This product will NOT work on right-hand drive applications. This CAN be used with stock/factory cat.

Long over due review

I’ve had this open dump down pipe since around 2016. Car has ran and sounded amazing. Recent times dump tube broke off. And sent it for repair. High happy over the repair and turn around. Finally used the warranty and completely satisfied. Been buying from map for ever and will continue doing so.

Fantastic product

Ordered at night, shipped the next morning and received the day after that. Great customer service and the downpipe is top notch.

Nice open dump

Great looking pipe. Weld where on point. Was a little of a pain to get in due to turbo placement but with patience it went in nice. Definitely recommend having a lift when doing it. But all in all not mad at the purchase. It’s definitely a screamer!!!!!!!

Fantastic Upgrade

Great and much needed upgrade over stock!
