What size primaries for LSA exhaust?

Hey guys.
Making up a custom exhaust for my LSA.
Just wondering what size primaries are recommended for long tubes and what effect it has (power restriction or just power band?).
Eventual power goal will be around 750fwhp

Not 100% sure, but by it being a blower car I would do 1 7/8

Minimum 2" if you're going through the trouble. It's practically impossible to "over exhaust" a blower car.

1 7/8 will get you no where.
