About to purchase a F.I. Exhaust and HFC Question

I'm fairly conservative....

So I kept the stock cats and went with the 18" res option.... after about a month of use, it just seems a lot quieter/maybe it's me. It's almost stock sounding above 4k rpms unless maybe at full throttle, and even so, it's seems about only 20% louder than stock at best.

So now I'm entertaining HF resonated cats ($700) vs. non res x pipe ($???) (if you had to pick just one), which is probably going to be a low rpm drone vs. high rpm fun decision.

Just wish it was a Porsche flat six...
