is this popping normal with the axle backs? do any other have the same popping?
for those that have the GMPP touring (not offroad) do you have the same pop?
also do you guys have any drone? it seems to hum some at 75 mph and 6th gear, but any higher rpm's it goes away and if I drop to 5th it gets a little better
thanks

I just installed SLP Loudmouth II's axle back and I get the same popping and occasional drone at certain rpm's, all is normal.
