Engine Masters Season 7 Episode 7 Manifolds or Headers?

In Engine Masters season 7 episode 7, titled "Manifolds or Headers?", the hosts explore the different ways engines can be improved with better exhaust systems.

The episode begins with a brief overview of how exhaust gases are produced in an engine and why it is important to expel them efficiently. The hosts then dive into the debate of whether manifolds or headers are better for performance.

First, they take a look at stock manifolds and explain why they are not ideal for high-performance engines. They then compare them to aftermarket manifolds and show how they can make a difference in power output.

Next, the hosts move on to headers and discuss how they can improve exhaust flow and increase horsepower. They explain the different types of headers, such as shorty, mid-length, and long-tube headers, and which ones are best suited for different types of engines.

To test the theory that headers are better for performance, the hosts conduct a series of experiments. They compare the power output of a stock engine with its original manifolds to the power output of the same engine with aftermarket headers.

The results of the tests show that headers do indeed increase horsepower and torque, but the hosts also note that there are downsides to using headers. They explain that headers can be expensive, they require professional installation, and they can cause clearance issues in some engine bays.

To round out the episode, the hosts offer some tips for choosing the right exhaust system for different types of engines and explain how to avoid common mistakes when upgrading. They also discuss the importance of tuning the engine after installing a new exhaust system to ensure optimal performance.

Overall, Engine Masters season 7 episode 7 offers an informative and entertaining look at the debate of manifolds vs headers and provides valuable insights for anyone looking to upgrade their engine's exhaust system.
