Review MOPAR Dodge Chrysler Ny Exhaust Manifold fits 400 440 1974–1978

The Mopar 3830820 exhaust manifold is a high-performance aftermarket part designed specifically for 1974-1978 Dodge and Chrysler 400 and 440 engines. This manifold is an essential upgrade for any enthusiast looking to enhance the power and performance of their classic muscle car.

This exhaust manifold is a 4-bolt design, meaning it utilizes four bolts to secure it to the engine head, ensuring a strong and reliable connection. The manifold's primary tubes are constructed from high-grade stainless steel, which is known for its superior strength, durability, and resistance to corrosion. This material selection not only ensures a long-lasting performance but also adds an attractive aesthetic appeal to the engine bay.

One of the most notable features of this exhaust manifold is its unique collector design, which utilizes a larger primary tube diameter compared to the original factory manifolds. The increased diameter allows for better gas flow and a more efficient exhaust system. Additionally, the collector design helps to reduce exhaust backpressure, which in turn can lead to increased engine power and torque.

Another significant advantage of the Mopar 3830820 exhaust manifold is its compatibility with aftermarket high-performance exhaust systems. The manifold's large primary tubes and collector design make it a popular choice among performance enthusiasts who are looking to upgrade their exhaust systems with bigger, more efficient headers and mufflers.

The Mopar 3830820 exhaust manifold is also designed to be a direct replacement for the factory exhaust manifold.

The manifold comes complete with all necessary gaskets and hardware, ensuring a seamless installation experience.
