ATP Turbo Divorced Transformable 3" Downpipe | 2008-2016 Mitsubishi Evolution X (ATP-VEVO-023)
Divorced 3" Transformable Downpipe for the Evo X by ATP Turbo
The divorced and transformable 3" stainless O2 housing and downpipe assembly for 2008 and up Mitsubishi Evolution X (10) is a much higher flowing replacement for stock restrictive cast iron exhaust elbow and small diameter downpipe just before the cat. This unit bolts right up to the stock turbo and facilitates a greater amount of exhaust flow out of the turbine while reducing the amount of turbulance in the erea near the turbine wheel discharge.
The result is much quicker boost response throughout all gears, big gains in torque and much higher HP all the way through redline. Even when mated to the stock exhaust system, we saw huge gains due to the increased exhaust flow. We also saw lower EGT's which above and beyond the power and torque gains, can increase reliability on the EVO X engine.
This unit is constructed of a thick 1/2" CNC machined discharge flange, 304 grade stainless mandrel bent tubing, a high flow 3" stainless flex joint, and TIG welding for better appearance and durability. 02 bung is also in place for factory 02 sensor. The unit is totally optimized for flow while retaining the compactness so you can re-install the factory stock manifold heatshield.
To further protect your investment on this 02 housing/downpipe assembly, we have designed this unit to be "transformable' to be used with an external wastegate. This additional feature allows you to simply (through a seamless process), disable the internal wastegate and install a Tial V-banded 38mm or 44mm wastegate at will (and literally on the fly). The process allows you to go from internal to external gate without removing the 02 housing/downpipe once it has already been installed. Those who have used external wastegates know that going from internal to external wastegate allows for far more precise boost control and increases the overall reliability of the entire turbo/engine setup due to the better controllability.
Internally wastegates are generally more "convenient" to use but tuning a high HP / high boost turbo setup can sometimes involve the process of "boost curve chasing" where dangerous "overshoots" or disappointing "drop-offs" can occur when trying to "dial in" the boost range. The external wastegate (especially the Tial V- banded units) allows for more precise boost control and has an abundance of spring pressure combinations that allow you to set boost levels much more easily with greater precision. Adding the exteranl wastegate onto the EVO X engine will result in additional HP gains above and beyond the 02 housing/donwpipe itself due to better exhaust breathing.
PLEASE NOTE: External wastegates and flange options are available. These additions are extra.
