Mitsubishi Lancer Ralliart 4B11T Direct Replacement Exhaust Manifold

Sale price$1,569.00


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.
