Nissan 370Z Forum - Best sounding exhaust with berk hfc

hey guys i currently have full berk system. berk catback and berk hfc. i love the sound but just putting it out there what setup wih the berk hfc would make my note deeper..its loud enough i just want it to be deeper. motordyne wouldnt fit with berk hfc right?/ thats what ive read on here. maybe FI...but how many inch resonators? maybe ark? and i really found an invidia cbe for a great price but i heard invidia with berk hfc sounds like complete crap. and thats from one of the forum members with the grey 370z. i know invidia sounds amazing alone or with invidia TP but not with berk??
