Engine Masters S08E26 - Header Science: Step vs. Merge

Episode Overview

There's a hidden magic in the world of exhaust systems that can either enhance or diminish power. The team delves into the advantages of stepped headers, which feature primaries that increase in diameter, and merge collectors that intentionally restrict flow at the collector. They compare these to traditional, straightforward headers. Do the claims about frequency tuning from these stepped designs and the velocity-boosting merges actually impact engine performance? Without a doubt!
