The exhaust manifold of the TurboWorks company is made of 100% stainless steel.
When performing engine tuning, the exhaust manifold should be replaced at the very beginning, because the exhaust gases, extruded from the cylinder, are sent to the exhaust manifold, which is part of the engine body, then are directed to the first section of the exhaust pipe, and then to the silencer, or several serial positions mufflers and then to the outlet port of the exhaust pipe.
The set includes a set of gaskets.
Adjusting the exhaust manifold leads to reduced back pressure, resulting in faster cylinder flushing and improved exhaust flow. They recommend wrapping thermal insulation tape before installation.
