Yoshimura now makes the R-77 and R-77D slip-ons for the FZ8.

So I contacted Yoshimura with a couple questions I had about their FZ8 pipes. Here's my message to them:
"Hi, I've been looking at your exhaust options for my 2011 Yamaha FZ8 and have a couple questions. First, which muffler has a louder exhaust note, the R-77 or R-77D? From what I can see in the pictures, the R-77D looks shorter. Do you have the dimensions for each
muffler? Thanks for your help."
And their response:
"
@ 5000 rpm------OEM-91.9dB ------- R77 w/insert-99.8dB ------- R77 open-102dB
They are both 12" long for your application. We did not sound test the
R77D but typically they sound about the same as the regular R77 with the
sound insert
Thank You,

Not bad for a Yoshimura exhaust. I did read in my SSB magazine that the Yosh R-77 pipes were designed to meet the EPA noise emission requirements of 80dB. Clearly the above statement from Yosh shows that they're well over 80, but so is the stock muffler, but thats at 5Krpm. Anyway, I think this sold me on getting a Yosh R-77 carbon.

Yeah funny thing is I sold my Speed Triple 2 years ago, cause I knew it was a matter of time before I lost my license (got caught 3km/h short of getting my license suspended for 7 days...and I was in first gear...they juts caught me in full acceleration). The FZ8 has less power, and it sometimes makes things worse, as sound and torque start getting interesting when you're already way above speed limits in the city. With the SPeed Triple you'd just wheelie yourself to 2nd gear and get that huge torque right from the get go. Not even thinking of power wheeling with the FZ8...for now that is So I think having that lack of torque down low is just making things worse for me I just rev it high and enjoy that air intake sound and growling...
