Oh and for the OP, if you compare the tread width of your choices you will note that PSS is wider by an inch for the 305. Kinda odd since the narrower sets (285) don't seem to have that much of a discrepancy.

yea the PSS runs odd compared to most 305s I forgot to mention that earlier. very good catch.

as for the exhaust my exhaust with no cats and mufflers was loud but ok.

my exhaust with no cats and with no mufflers. nonsense.

the FI mufflers really do a good bit of sound reduction lol

I
d say drop cats for power and keep mufflers to be legal for SCCA
