So I have Borla exhaust and borla UEL headers on my FRS. I've had the exhaust for about 10 months and the headers about a month. It was decently loud after header install and good rumble but now all of a sudden it is like the headers aren't there.... It sounds really quiet barely can hear it while driving, unless in high Rpm's. It sounds similar to when I only had exhaust, little to no rumble. I don't have any loss in power just exhaust loudness? Please help
