Hi
I am in the process of upgrading my exh header
What is the stock internal diameter?
And what diameter would you recommend for fabricating an upgrade?
Thanks in advance

i'm unsure of the stock size since each runner tends to vary. but 32mm NB (1 1/4inch) pipe would be the ideal size as it matches up to the ports and will flow enough gasses for good power without making it laggy.

Thanks a lot
Its been fabricated with 1 1/4 primary tubes, and now the turbo is high mount
I had a low mount ct9 unit with 2 1/2 dump pipe
Too restrictive for a 1.6l (I have a turbo carbed e16)
Hope to do the upgrade today
Ill come back with pics
Peace
