Yoshimura R77 Full Exhaust hp

[Shean]

Hey do anyone knows what kind of hp the yoshimura R77 is giving out. That is the full exhaust. Heard it wasn't giving out that much just wanted know because this is the setup I have on my Busa.

Only way to know for sure is to put it on a dyno. But to be accurate on your power gain, you need a "before" reading. Find a place, get a print out, post it on here for us to see.
You live in Chicago, there are several dynos to be found there (to say the least). Go hunting.

PS.. For comparison, last spring my Gen 1 made 149rwhp, completely stock, with 4 month old gas, 1400 miles on it, on a "conservative" dyno.
