White Bros. headpipe for 300ex question

[skull]

I'm using a Pro Circuit T4 silencer with a stock headpipe on my 300ex. I was wondering if the White bros. header would fit and connect properly to the T4. anyone know?
anyone know if the White Bros. header would connect to the stock silencer? that may give me some indication.
the reason I want to know is, the White bros. header is like $100 cheaper than the Pro Circuit.
what kind of gains could I expect with a header? more torque?

It should work. The bends seem to be the same other than diameter and where it comes out of the head is drastically different. I have one with an E Series silencer. The gains I noticed was lost a little bottom end, but mid-range and top end were big gains. Hope this helps!
