S&S gnx 4.5

Hi all, considering a set of the above to mate up to my powertune headers. Bikes a stage 2 96” Wondering the effect of the db reducer on performance. Volume isn’t an issue were I live and I’m ok with a lil louder I just don’t wanna sacrifice performance or torque either way. What is the positive and negatives of the db reducer and the opinion of using it at all?
thanks

They will work very well on your bike and if you leave the DB reducers in your neighbors won't notice you going by.

Thanks , I’ve heard good things about them from my tuner but in regards to the m8. He assumes they’d do as well with the TCs. I’m just curious about the role the db reducers play. Regardless I guess I will find out as I just ordered them. So I’ll find out.
