The "rasp" is killing me.

The "rasp" is killing me.
My exhaust is in my signature. It is driving me absolutely insane. As soon as I hit 3k, it starts to make like a "rasp" "buzz" noise, it's seriously incredibly embarrassing. It NEVER did this when I first got it, and it has only been on the car for 3 months now, why does it do this now?
It is a magnaflow resonator and a magnaflow muffler. It is a well built setup, full v-band, if you're wondering where the flanges are.
Here is a picture. The resonator is WAY too small (I think, which is why it sounds like ass). But my question is - Where would the middle hanger (circled in red) go if I add a bigger resonator..? And what is a good resonator? It is cat-less.

Part of the rasp is being catless, but exhaust do take a bit of time to break in if that makes sense. Like after about a week the tone will change a little bit. But it does seem now 3 months later that it's rasping.... Sound clip maybe?

I was looking at a Corsa Touring cat-back, but I'd rather just keep this one. I like my full v-band setup. It's very nice.
These pictures are old BTW, taken last November, I just used it for reference.

mine does this to...drives me CRAZY! ive found driving the car different ways makes it better or worse. i do however have a header,cat, and exhaust and mine still does it.

Either the baffles inside of the resonator or the muffler are shot. It sucks but exhausts only last a couple years before they become loud, especially on a performance car with high EGT's.

my muffler dont have packing in it, so i think if i had the same muffler with packing i would be alot more happy.

Magnaflow mufflers are known for doing this. Not insulting them, but it's very common with them that within 3 to 6 months the sound quality degrades dramatically. Even the V8 setups.
Having no cat won't help. If your dead set on keeping it I'd swap the muffler.

No cat presents serious problems for us. You will need to fit like a 30inch IIRC, resonator. Preferably 4-5inches in diameter (it might hang a bit), and you will need to run a super turbo-type muffler.

my magnaflow does the exact same thing ur describing except i've got all stock piping from header to tip just with a magnaflow muffler, sounds like a$$holes from like 3k-3.5k rpm

Hey shadow, How is the lth from zzp, I got the catless to a 2.5 bolt on deal. Did you have any leak at the Vband?

exactly. My buddy has a magnaflow and hates it. I personally would never touch anything magnaflow...ever.

I'll have to check that tomorrow! It sounds like it's from the muffler for sure. I've been paying more attention to it lately and it's definitely from the rear of the car.

what resonator are you running? I think I am going all 2.5 on my catback. I was thinking of using their 2.5 tube muffler paired with that muffler, that tube deal supposedly can be turned around so it gives a deeper throatier tone. Sorry for the thread jack.
