Well, the exhaust is filling up with fuel, that is what causes a muffler explosion. That kind of makes me think you are excessively rich. Did yo check any codes or look at the number one spark plug?

I wonder if you are not getting decel fuel cut for some reason.

i did check for codes and the only code i got was 51, and also there is no boost or vac. leak my freind just told me to check my throttle body to see if its clog but it doesn't seem like it and check my intake/IC pipings for cracks or so but didn't find none.
