Regarding the build, I think both the exhaust and the inlet are the restrictions. Right now, you are definitely pushing a ton of exhaust through a restriction. BUT you are also sucking through a straw trying to feed the big blower.

At 700rwhp+ the 103 and BG start to become very beneficial. I'd say even more so than the headers. Especially if you increase the blower speed with pulley changes. The 2650 will be trying really hard to bring in air through a small opening.

So yes, the headers will help get rid of outlet restriction, but you also have an inlet restriction, particularly if you increase blower speed.
So to conclude, do both at the same time.....
