OUTLINE
An exhaust pipe that accommodates a high-output engine has been adopted as the exhaust system for a new generation of rear-wheel-drive sports cars that combine sports car performance with efficient fuel consumption.
In ongoing efforts to provide more power with good vibration performance, the muffler has been made as small and as light as possible.
A stainless steel exhaust manifold and exhaust pipe have been adopted to ensure lighter weight and good corrosion resistance.
Catalytic converters are located in the assembled section of the exhaust manifold (integrated exhaust manifold) and front pipe to ensure adequate emission performance. Emissions immediately following engine startup (in cold start) have been lowered by the catalytic converter used in the assembled section of the exhaust manifold.
Loss of exhaust pressure has been reduced by optimizing the exhaust pipe diameter, and engine output has been optimized.
An wide range air fuel ratio sensor has been installed upstream from the exhaust manifold's catalytic converter, and an oxygen sensor has been installed downstream from the exhaust manifold's catalytic converter, enabling fine air-fuel ratio control.
