I would like to know if they help out performance wise or if they just cause a bunch of unnecessary noise. Thanks.

Basic research shows that bolts on in general on a D series do nothing.

Assuming you have a D series as you have provided us with zero information regarding your set-up.

sorry for the lack of information, but you are correct. I am running a
d16y8 with dc headers and a magnaflow exhaust system.

A header is a supporting mod. By itself, even with a tune, you might see a 5-7 bhp gain, maybe. It also looks a hell of a lot better under the hood. The benefit to the specific DC header is the CARB stamp. If you don't need a CARB stamp, a header is a header.

^I agree, however you must also consider build/material quality when making a purchase.
