Got a slip on installed, AIS removal neccesary?

Hey, i got my new yoshi rs4 installed. No popping or backfires.

Should i remove the ais anyway? What gains besides weight lose?

Does blocking the ais pipe from the airbox increase airflow since it no longer flowing air to the header ?

I had to remove mine after I put the fmf q4 pipe on it, it was popping when I let off the gas.
Other than the popping which your not getting, all it does is save a pound or so of weight when you remove it, it has no effect on power.
