Extractor Flange Question? Small 3 Bolt and Large 3 Bolt

Do you Get more Performance on a 1600cc Mild engine from a Small 3 Bolt Flange extractors or Large 3 Bolt Flange?

Or Is There Not much Difference?

From Dylan

go the smaller one

Yes
I agree,
You are looking for extraction of gases... Extractors...

so the smaller ones... extract better than just a large pipe...

You'll find the pipe size is bigger on the large flange if they are EMPI headers.

The large 3 bolt is 1.5 inch and the small bolt is 1 3/8" which is ALOT better for a mild 1600,
if you went to big you'd find you'll loose some of your bottom end, which with your single carb is where your going to perform best!
