Installed an AFE Vulcan cat back exhaust and have a harmonic ringing at about 1.9k RPM on acceleration and deceleration. Sound reminds me of a glass that you rub your finger on the rim to produce a sound. Has anyone ever experienced that or figured out a solution to fix it other than going back to stock exhaust?
