Exhaust buzzing sound

I just installed my Dinan mufflers, and everything's great but I seem to have this metallic buzzing sound right at around 2500rpm.

I thought it could be due to the muffler cans hitting the heatshield but there is plently of clearance all around.

I've had this sound with my Gintani race and my Remus sport. Both of those were also only at a certain RPM.

Anyone have any idea if this is normal or if there's a fix? Maybe the exhaust is hitting touching something that I overlooked?
