i have ppe LTH and greddy gt evo. i used to wear earplugs on the highway because of the drone levels. literally unbearable over long trips. anything from 2500-3000 rpm was hell. music above 3000rpm. ive since switched back to my hks hipower which is pretty much silent on the highway yet still makes a good noise when your into it.
