Muffler upgrade

Hey guys just upgraded my stock hawk pro muffler with silent power, Question is should i have to adjust the Os 37 engine? I seems to be running a little leaner, The muffler gets really hot compared to the stock one and the engine only a little warmer. The muffler is a lot quiter and sounds great.
