That has absolutely nothing to do with headers. Did you mess with the ABS actuator at all? Check all of your connections, and double check anything you might have disconnected or taken out to install the headers.

Kinda late but I just started having the same problem and instantly knew what it was.

The driver side header is rubbing against the rod coming from the steering wheel to the steering rack.

I know that because I got the same cheap eBay headers as well and was there during the installation. They are not built to specs, mine had to be dented in order to fit without touching that rod.

And the worse part; the damn headers ain't worth ****... Got way more gains from installing a plenum spacer. And i installed that one myself, not hard at all.

The 2 components are totally independent and not related. Re-check your work.

One a trained mechanic can research the issues and correct them.
