Exhaust sound terrible change

Hi all, my exhaust sounds extremely different now (Flowmaster Outlaw catback)!! It sounds raspier and uglier than before. The cracking/popping sound after letting of the throttle is completely gone, it just sounds like a drone through the rpm. It was a night and day change, one day it was perfect like always and the next day this all happened.

Ive had my exhaust for barely 9,300 miles and my car has 19,500 miles.

What could be the reason behind that?

Like as not you've snapped a baffle inside one of the mufflers. Flowmaster isn't super high Q stuff to begin with and is naturally predisposed to drone.

How can I check if a baffle was snapped? The problem is in both mufflers, as they both sound bad so I think its unlikely that both have snapped

Save your money and get Borla!!!!!!!!! I thought I had a crack in mine because I herd a rattle noise. it ended up being something totally different but they still sent me a NEW exhaust for free. life time warranty.

Outlaws are resonated tubes so I don't think there would be baffles

Get under the car and hit the mufflers if there's water in there you'll hear it move around. You'll have to hit them kinda hard.

Drive the car you'll either blow the water out or it'll get hot enough to get rid of the water. If you drill a hole any type of warranty on the muffler will be gone.

Kinda like these guys said what I would do first is get a strong vacuum and put it in each tail pipe and then a high psi air tank.
Suck and pull, listen for something broken.
Or, get yourself excited and choose a new set of mufflers, remove the one you have and send them back to FM. If they send you new ones, sell them.
PLEASE, go to DR GAS and listen to his mufflers and catbacks.

I would really hope he'd already have it corrected by now.
