ok so i was driving home from school today and my check engine light has been on for a week and a half cuz of the new high flow cat i put in. i was told that it wouldnt hurt my car to run with the CEL on. i was gonna fix it tomorow with the O2 simulator i ordered. but today as i was driving there was a loud clunk like a rock went through my exhaust system and out the back. i looked in the rear view mirror but nothing fell out. my car sounded really wierd and raspy when i pressed the accelerator so i pulled over and checked out my intake and exhaust and nothing seemed wrong. but my car sounds so horrible and the throtle response is bad, and its not as powerful. anyone please help. i dont know if it was a backfire or something broke lose or what.
