exhaust leaks not only let exhaust gas out they often "suck" fresh air in between exhaust pulses, usually at idle and lower rpm on\off throttle
as your leak is near 02 sensors it can effect 02 reading as it sees fresh air with high 02 content so signals ecu to add fuel to engine as it thinks its lean, but your going to run rich due the unneeded fuel hence the fuel smell
log your long term fuel trims and commanded afr verses afr.
