What's the difference between 4-2-1 and 4-1 headers? Does 4-1 give you better top end power over the 4-2-1?

 

421 are easyer to instal, and also give better ground clearence, and 421 gives better low end and 4-1 gives better high end.

 

these kind of questions are no longer valid questions... now-a-days we have so many varieties of headers to choose from it's not even funny. we can choose from the $100 header on ebay to the $800 header by the very reputatable people on this website.

there are variations in the 4-2-1... you have the original and now you have the tri y design.

i think the question you should be asking yourself is... "how much am i willing to spend... for a header"

 

heres a really techincal answer to your ?
