Exhaust gases exit the exhaust ports into the inboard exhaust manifolds and are directed to the dual turbine inlet of the
turbo through the right and left side up-pipes. The exhaust gas and heat spins the turbine wheel inside the turbocharger.
The turbine wheel spins the compressor wheel(s) via their common shaft. Some of the exhaust from the passenger side
manifold is directed to the EGR valve through the EGR inlet pipe. When the EGR valve is being operated, exhaust flow goes through the valve and is routed through either the EGR cooler or bypasses the cooler. This is done by the EGR cooler bypass valve. The exhaust gas enters the lower intake manifold and combines with the fresh air.
