Look for the motor stamp...
I dont think 99-00 Ex's came with a Non vtec motor. I think only the HX-CX were the only ones to come with a Non Vtec motor. Correct me if im wrong.

the noise your hearing at 5k i believe is your secondary runners opening up. the "vtec" option on sohc motors is more for good gas milage than performance
