I had headers and a Borla installed about a year ago. The sound from outside is great! Nice low growl. I've listened to it as my wife drove it to work a couple of days. I like!! Inside the car is another matter. It's loud...... sometimes. There are RPM zones where it's pretty annoying and others where it's mostly quiet, or at least not bothersome. EG..between 2500 - 3200 (or so) it's pretty loud. Quiets down above that, even under acceleration.

OH..and I had the Borla on for about three months before I got the headers installed. Not much difference in sound before/after the headers. But, there's a noticeable difference in low end grunt before /after. (After being better)

Do I like it? I'd say 50-50. I am usually in the car alone and keep the rpms above 3K. So the drone is gone most of the time. The problem arises on the open road trying to keep to a speed where the rpms are out of the drone range. Not always possible. Not sure I'd do it again.

Hope this helps.
