2” Header

[big d chop]

what kind of power do you need to run a 2” header on your race engine , when I had my old 1914 engine I used a 1”7/8 merged exhaust and a lot of people told me it shouldn’t have worked as well as it did and that it was overkill so I thought I would ask  about a 2”

Cheers

On a 1914 engine i would run a 1-3/4 . we use this up to 240 HP with 2,3 engines  2" is  too big
