Artec Performance Direct Replacement Exhaust Manifold (Ralliart)
Artec direct replacement cast stainless steel turbo exhaust manifold for the Mitsubishi Lancer Ralliart 2009-2015.
The biggest flaw on the factory manifold is only 3 runners reaching the collector even though its a 4 cylinder. 2 runners were merging just before the tight radius in the turbo flange area. The cracks were appearing along where the y runner met the other 2 runners.
This is because twice the hot air flows in the same diameter pipe, resulting the runner with a much greater hot spot which causes it to expand more. So where it was cracking is where the metal is moving the greatest amount.
So when ARTEC was designing this manifold, they removed the particular hot spot by removing the restriction and/or bottle neck caused by the tight radius’ to increase flow.
Made from 347 Stainless Steel, the runners have an inner diameter of 33mm, this combined with the longer radius’ keeps response up by reducing manifold volume, but also keep flow up.
Features:
- Cast 347 Stainless Steel Material.
- 33mm ID runners.
- Retains the use of the OEM heat shield and hardware.
- Direct replacement for factory turbo manifold.
Application:
- Mitsubishi Lancer Ralliart 2009-2015
At ARTEC they have revolutionised the turbo manifold industry with their industry leading SUS347 stainless steel investment cast manifolds.
All of their 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 them 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.
