Yoshimura Japan Slip ons?

[Batfink]

I have the R77, SO/SS/SS/CF on mine, so dual slip on, stainless body, carbon ends, and I love the sound.
Not too loud, not too quiet.
Saves a bit of weight, but not as much as you may think.
According to a Yoshi dyno report I found recently, they actually lose 2 hp over the stock pipes if nothing else is changed.
Still worth the trade off in my opinion.

I agree Lucky... Love the note of my R77 slip ons

note: they do come with a baffle insert if you want to sneak past the
