Big day for the Busa. Have some questions though.

Put on a Roadsmart 2 and my new Yosh R77 carbons on my K9. Much louder than I expected and oh what a sweet sound they make!! A couple of questions though.

Do the noise reducers reduce power? They didn't seem to make that much difference in the sound so I left them out.

Do I really have to repack every 5000 miles like the manual says or can that be stretched?

Is there a repack material tht extends that interval?

I have the same slip on's, no noticeable difference In the seat of the pants dyno.

Yeah, I think it's much faster but that's my wallet talking She does seem to rev a little easier. Sounds incredible though!!

I've got 10K on my R77 carbons without a repack. They sound better every day.

Check the Yosh website, but I would imagine that they would reduce performance, but I doubt you would feel the difference. Not a tuner or exhaust engineer.
