I'm running the Graves stacks and at 4000 to 4200 RPMs the intake is louder than my Yoshi full exhaust. Thinking about putting the stock stacks back on.
I just ordered those Looking forward to hearing that

Graves, Copperdawg or Ivan's all have them (not 100% sure about Graves)....
..... or you can mod them yourself. Remove them, score the edge to mark a 38mm diameter ring, cut close to the line with snips (very soft metal and easy to cut), then stack all four together with small nuts and bolts and file the edges smooth down to your scored line all the way around. Take each one and smooth the two faces on some fine emery cloth to remove any edge burrs... install!
They shift some available HP from the very top end down to the mid range where we live and ride daily. You do lose a tad in the bottom end. Just be sure your idle is set for 1200 to 1350 RPMs and it all washes out.
If you are going with the stacks, I'd recommend headers, air filter and airbox mod to let the beast breathe.
