Body Damage is Cool

My recently purchased '89 4runner 3.0 V6 starts and idles well, but has less power than my 22RE truck and runs a little rough under throttle. I haven't really had time to do any troubleshooting yet, but I noticed the the exhaust pipe has a fairly big leak in it just upstream from the O2 sensor. Any ideas on how likely that is to cause the motor to run like this? No check engine light yet.

'89 4runner SR5, 3.0, auto (fun)
'93 xtra cab, dlx,3.0, 5spd (work truck)
