Been there, done that. Cool for volume/flow, but not rasp

Sold my SuperSprint unresonated S-pipe a while back and put the OE section1 back in to control the God-awful rasp.
How do you find the rasp now?
I'm doing headers in the spring & that's my one concern.
I don't mind a bit of drone, but I hate rasp.
