Default 71 running rough

i just got a 71 out of storage after 9 years and it is running rough. Kind of what I expected but what seems Strange to me is that with dual exhaust I get a lot of exhaust out of the passenger side and not much out of the driver side. I put my hand there and can feel it but there is more on the passenger side. It also seems to be backfiring a little and it seems as if it is on the driver side only. I guess something could have made a nest in the muffler but not sure how to diagnose this

the weather was was cold and the exhaust was whitish so not sure if it was just cold or if it was coolant but only on the passenger side. Would a compression test be a good thing to do

any suggestions
