Just curious, but does anyone else's exhaust "fart" when they shift at high RPMs? Not the typical buzz can sound, but a loud, obnoxious kind of noise that sounds like someone stuck a kazoo up their a@$ and let one rip. It's done it since the car had stock exhaust , it did it with the Magnaflow muffler, and the Dynomax, and now I have all new 2.25" from the cat back, straight through with an HKS muffler, and it still does it. I thought it was the exhaust rattling on something but there's no rubbing going on that I can find. It's getting really annoying and I'm wondering if a glasspack would stop it, or maybe a different cat and header. I'm planning on adding a header and cat anyway, but if I can't make my car stop buzzing like this it'll be sooner than planned cuz it's actually sort of embarassing.

Mine kinda does it but i have no muffler on my car , add a resonator to your car and it will probably go away pretty quick. I kinda like my car being alittle annoying since the town i live in is full of tourists in the summer and none of them pay attention, my car being loud gets them focused rather quick.

ive noticed on both of my cars with tuner exhausts, that they gurgle when u let off the gas, is that a problem

It's not the typical exhaust popping, its a funky high pitched buzzing noise. The "gurgle" you're referring to is normal with any performance exhaust, this is something entirely different.
