[QUOTE="FIREBALL, post: 15640553, member: 178539"] After 9 months since i posted this thread, here is what ive figured out so far. As it turns out I hear this pop pop burbling knock sound that is at the tail pipe only and mostly on the right side only----------Well I have noticed that I hear this on all modular fords with straight through exhaust, I have even heard it on a 2014 Shelby Cobra Mustang with the 5.4 supercharged. I even hear it out of my Ford F150 5.4 with single exhaust but not as noticeable. RX1Coabra above says he hears it from his all the time. So I know its not an engine knock but it drives me crazy because for me it ruins the sound of my Magnaflows at Idle and low speed. After alot of searching on this the best that I came up with is that the sound may be related to the E.G.R. valve, but I dont see how that could be. Anyways Im thinking about putting my stock mufflers back on to lessen that noise. I brought this to the attention of that Shelby Cobra Owner, he said he had never noticed it but now that I pointed out to him, he says it is driving him crazy also. LoL. Any other ideas or thought on this?? [/QUOTE]
