    Stainless Steel External Dump O2 Housing

    If you're having issues with boost control and/or boost creep in your Evo 8/9 recirculated o2 housing then this product is the answer. It has also been shown to yield significant power gains when combined with larger stock frame turbochargers!

    This unit is 100% stainless steel to avoid rust and corrosion and includes a money back guarantee in regards to lower intercooler pipe fitment! It will bolt up to any stock Mitsubishi Lancer Evo 8/9 turbo location. It's made of 2.5" diameter piping and includes a stainless steel gasket from the the turbo to the housing and one spring bolt to ease the installation process. All other OEM hardware can be re-used for installation including the OEM donut gasket.

    CNC 3D Contoured Flange

    This product featuers a 3d contoured flange to virtually eliminate boost creep regardless of boost level or turbocharger sizing.

    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 protect 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.

    Good quality but...

    Good quality welds. Sounds great when the wastegate opens. Clean look when installed,but... I did have to hammer the AC line alittle towards the front (it bends really easy so that’s not a big deal) for it to fit and I would recommend buying a different gasket to mate with the turbo because mine was leaking from the get go. But other than that,it’s a great product!

    Quality parts

    Good quality welds. I like it how they port out the flange to match the gasket. The wastegate pipe doesn't have that reduced pipe welded near the flange like the one in the picture shown which is a +.
