I want an exhaust setup with the power gains of being catless, but good sound that isnt completely barbaric. Would this combo be good for that?

i've never heard/seen an HKS silent high power, its a new style muffler, and most people seem to just default to the RB stuff

Well of course. The point of this thread is asking if anyone has experience with this combination of parts and would give input as to whether it would be reasonable for a street setup in southern california. Or alternatively if anyone has any other possibly better alternatives.

I have had it before , as well as a handful of other exhausts. And none of them are what I would consider "reasonable" without a cat or resonator replacing it.
So the answer to what would be a good sound without "being barbaric" is any combination of cat/center resonator + JASMA rated catback. Dual systems will always be quieter than single systems...
My personal pick if you want to take the time to find one is the Fujitsobo Legalis R . Higher flow than stock but quieter over 3000RPM it would probably be the most tolerable exhaust made with no cat. No joke, the sound data shows it to make LESS noise than a stock exhaust but still giving a "dyno tested" 6hp gain on a stock car.

That's the point I was speaking to. The silent Hi-Power is one of only a handful of exhausts for FC's that are JASMA certified meaning they meet the strict noise guidelines Japan has.

The silent HiPower is one of the quietest bolt on exhausts for an FC, but without a cat it's still going to be pretty noisy. It's about on par with a honda with a fart pipe for noise. There's just no way around that without a cat or presilencer.

Yes and it was mildly aggrevating.
