Unfortunately, that is the downside to changing to HFCs. Nothing wrong with the exhaust or car. The non-resonated are louder than the resonanted. But some people cannot deal with the hiss at all since it is their daily driver and revert back to stock cats with just the catback exhaust.
I have Berk HFCs non-resonated with FI exhaust 18 inch resonaters. Loud hiss but louder exhaust.
