Exhaust manifold under turbo designed for:

Exhaust manifold from TurboWorks, made of cast iron

When performing engine tuning, the exhaust manifold should be replaced at the very beginning, because the exhaust gases, extruded from the cylinder, go precisely to the exhaust manifold, which is a part of the engine body, then they are directed to the first section of the exhaust pipe and then to the muffler, or several mufflers in series and then to the exhaust part of the exhaust pipe.

We also offer lambda probe adapters to eliminate catalytic converter error.
