Default Flange Dimensions S91?
Trying to get exact dimensions for S91 exhaust flange.
Will be getting a Quick Spool Valve but want to confirm my dimensions.
Is there a source I can look up the different dimensions for turbo flanges?

Checked this against my S91 and the inner dimension shown as 4" is actually less, 3.5". Bolt hole is around 0.5" instead of 0.406".
