Greddy Evo not sounding right...

I woke up this morning and went for a drive, and my exhaust sounded twice as loud as it usually does. Also, it doesn't start off quiet then ramp up with the normal hum but makes a more universal loud sound when you are start accelerating. It kind of sounds like an old car's muffler, like its not flowing properly. Any ideas?

some days my car sounds loud, some days it doesnt. some days i think i hear my car making different sounds. if it doesnt hurt the way i drive or how the car drives, then i let it go. i think its just me nowadays being paranoid.

that happens to me to. its probably in your head.

LOL... I know how that feels.
