Really quiet, i don't think the power is too good considering how restrictive it is.

Yoshimura + Quiet core makes a pretty quiet pipe, about 95 db's I believe.

I haven't seen a dyno sheet but I know it's better than stock. Just really restrictive.

The powercore 4 is pretty loud. Not much to choose from when it comes to getting a quiet pipe, take a look at WB E-2 and WB E-series the e-series is quiet when you take out some disks (4 disks is stock sound) I heard that the WB-E2 is pretty quiet.

Yes it's a good pipe, not the best but it's up there.

Just my 2 cents. I put one on my 400EX last year, plus a K@N and outerwears. Re-jetted also, no airbox lid. Really opened up the mid/top end somewhat on my 400. Not overly loud, say, like a racing exhaust w/ no spark arrestor. Still louder than stock though. I see you can get a quiet core insert for it, if it's too loud for your preference.
