The divorced and transformable 3"
stainless O2 housing and downpipe assembly for 2008 and up Mitsubishi
Evolution X 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.
Vent to Atmosphere option also available, but is not transformable.
