Artec Direct Replacement Turbo Exhaust Manifold 4B11T-EVOX-DR-EX

At ARTEC we have revolutionised the turbo manifold industry with our industry leading SUS347 stainless steel investment cast manifolds. All of our manifolds are engineered and designed from the ground up, CFD simulated and, most importantly, tested in the real world to achieve maximum flow and heat dispersion. The cast stainless construction allows us to maximise flow and efficiency by having smooth merging angles and eliminating any restrictions from tight radius bends or runners.

The result is a truly optimised manifold with consistent performance, resistant to heat pooling and cracking, plus a beautiful smooth exterior finish. Designed and tested in Australia, backed with a lifetime warranty.

Artec direct replacement cast stainless steel turbo exhaust manifold for TD05 frame turbo for the Mitsubishi Evo X or Ralliart (with TD05 conversion). The factory manifolds are prone to cracking, and most of the aftermarket manifolds available don't provide a solution for thermal management.

Our manifold retains the use of the OEM heat shield, albeit raised up 26mm (1"). The lower heat shield mounts can also be retained if our 4"/3.5" dump / 02 housing is used in combination with our manifold. For the runner design, we have chosen to lengthen the center 2 runners to create a more equal length manifold design. This manifold uses 33mm ID runners to keep the ultra sharp throttle response that the OEM manifold offers.
