Default Exhaust sizing for l92 strokers?

I have a question about my setup. I hear alot of formulas saying things like after 400hp a 2.5in exhaust becomes a restriction, stroker engines need an even bigger exhaust, and that l92 heads need an even bigger exhaust since the flow sucks on the exhaust side. Well i still have the stock 2.5in exhaust, and i am wondering how much power am i losing, and would it be worth it to buy some electric cutouts where the exhaust is a 3in? It just seems to me like the stock 2.5 would be way to small for a stroked l92.
