Header to stock exhaust?

[LennysEleven]

Would it be a waste of time to put a header in front of stock exhaust?

Are there any better flower exhausts that arent noticeably louder than stock?

from what ive herd, headers on a stock or mostly stock m20 are pointless.

Supersprint and the IE Stainless cat-back exhausts.
