09 cbr straight pipe back pressure ??.....

i just recently cut the undertail exhaust off right under the rearset and was wondering how much my 09 cbr 600 needed as far as back pressure with out burning up my valves

you need a baffle of some sort, or the cops are gonna pull you over,
no backpressure will lag you on takeoff at low rpms.
i suggest making a shorty slipon.
