Quick Time Performance completes the exhaust puzzle for the Mitsubishi Evo 8/9 by introducing the External oxygen housing. A newly designed O2 housing that separates the waste gate from the turbine.The problem with the stock designed O2 housing is the waste gate gases are slammed back into the turbo exhaust gases which Causes a buildup of pressure and slowing down the turbo wheel.

With our External oxygen Housing, we separate the waste gate and run the exhaust gas externally to under the car. By accomplishing this it helps the turbo from creating any extra back pressure. Less back pressure equals more power. Besides the extra power gain you also get that awesome open waste gate sound!

With the Quick Time Performance Electric Cutout and the External oxygen Housing, you have the ultimate and most powerful Evolution exhaust system.
