ive done that with the remote start and i can hear it but i just cant locate the leak
and my service engine soon light came on and the code said low efficency catilist system bank 2
could this be from the exhaust leak or do i need new cats?

Ohhhh well it could be a bad down stream O2 sensor or one or both of the cats is bad and clogging up. If its clogging up then it will sound like its leaking exhaust somewhere. While its running does the exhaust stink real bad?? Go to the tailpipe and have someone rev on it and it may sound like its clogged up.
