cool thanks man. What exactly is drone?

yeah I had the super 44 muffler on and wanted it louder. so then i cut the resonator off and yes it is much louder while accelerating, startup, crusing. Its not much of a differnt noise tho. also expect more drone.

Hey man i have the i-Force 4.7 with a Flowmaster 40 Street Series. Did you have the resonator on there at the same time as the Flowmaster? Did it make a difference with noise? Just want to make mine a little more agressive and louder, but not like the nasty Z-71 stuff.
