These components are exhaust manifolds designed specifically for Pontiac engines, often found in models equipped with the Ram Air induction system. Their purpose is to efficiently channel exhaust gases away from the engine’s cylinders. These manifolds are typically constructed of steel or stainless steel and are designed with specific tube diameters and lengths to optimize exhaust flow.
The performance benefit derives primarily from reduced backpressure within the exhaust system. The enhanced flow characteristics can lead to increased horsepower and torque, particularly at higher engine speeds. Historically, these manifolds were often installed as aftermarket upgrades to improve the performance of vehicles originally equipped with less efficient factory exhaust systems.
