So a few weeks back I had an Invidia exhaust installed on my '05 fx35, and boy was it loud! I installed some sound deadening and that helped quite a lot, but when I'm accelerating to highway speeds it still gets kinda loud. So I was thinking of installing a resonator. I spoke to a local performance shop, and he recommended installing a Magnaflow resonator on each pipe (since its a dual exhaust). What do you guys recommend? Should I go this route, or do you recommend something else?
