Default Blown Cat

Title made me laugh too.

Went to the track today and made about 4 runs and noticed when pulling into my garage a loud rattling sound from under me. I leaned under with the engine idling and it seems to be coming from the driver side cat. I have a QTP Catted Y with the high flow Magnaflows. The sound is very similar to my brother's Jeep 4.0 when the cat went bad on it. I'll check it out more tomorrow and check back. I did notice the exhaust seemed a tad louder on the drive home.

Anyone else have this problem with the Magnaflow/Carsound highflow cats? They've been on the car for around 2 years now.

Well I checked it out further and it is definately the driver's side cat making the rattling noise. If you bang the cat with your hand you can hear it rattling around inside. Magnaflow/Carsound #94109. I don't get why it blew out. I thought they made them better than this. I'm stuck now, don't want to go back to an ORY and don't want to spend $$ on the same thing that's gonna happen again.

Anyone having luck with Magnaflow's #59959 metallic cats? Supposed to flow more than the ones I have now.
