Exhaust Manifold in Cadillac CTS vehicles is responsible for channeling hot gas that is coming from the engine to the exhaust system in an efficient manner so as to optimize the performance of the engine and minimize emission of dangerous gases. Depending on the engine layout, it is located in various places- the manifold helps to avoid reversion of intake which otherwise would worsen the airflow and engine efficiency. A typical Cadillac CTS model has employed various kinds of exhaust manifold such as the cast iron and the stainless steel exhaust manifold together with headers that offer superior performance as compared to the traditional kind of exhaust manifolds due to minimized flow resistance. Due to the fact that headers enhance one of the primary characteristics of exhaust gases, headers are most effective where velocities can be enhanced, which will result in improved engine power. Also, the recent technological innovations such as Yamaha's EXUP system have been incorporated in some of the CTS models to effectively control back pressure in relation to the engine's speed.
