The resonated test pipe from FI is also a option, since it's relatively cheaper than their HFC's, but I wonder how much louder it will be then with the HFC's? I'll be getting the 18 inch resonators from them if I decide to go with either setup in order to keep the sound level livable. Will the tone be different between the two?
