Question: motor sounds

I hear the lifters rattling when I am stop at stop signs etc.... It also sounds and sometime I feel what I best describe as compression lost, I hear mostly now that I have to replace my muffler. Could it be only due to the tail pipe needs replaced, or is it an engine compression issue, oxygen sensor? The sputters very lightly when slowly accelerating however if I get on hit on take offs there is absolutely no sputtering.
