stroker Sr exhaust size

[hashim]

I have sr20 stroker motor that I is currently making 500whp. I am bumping the boost up and wanted to know if my exhaust size will restrict it any? I am running a JIC magic 3 inch full titanium exhaust. I am looking to make 600whp with the new setup, any advice would be great!

Of course everything depends on your build. 3" will do but you would theoretically benefit from going larger. Even a little larger (.5" in the case of following article) will allow quicker spool, more boost capability, and more hp throughout rpm. 3-Inch Vs. 3.5-inch Exhaust Test - Tech - Modified Magazine (http://www.modified.com/tech/modp-1102-exhaust-test-tech/)
