Who makes the best HFC's without rasp?

I don't think the sound has anything directly to do with the cell count because I've been told and as far as I can tell the hiss is on Test Pipes also and even more noticeable and they are straight through..zero cell count. Maybe I'm wrong though and someone with TP can attest to the facts.

I just installed FI resonated test pipes along with the FI exhaust including the 18" CF resonators. There is a hiss with the whole system but it really is not that bad....very subtle compared to the low frequency growl...love that

That's exactly why the hiss is louder with test pipes. The lower the cell count the louder the hiss. This is why the test pipes have the loudest hiss.
