Well I took out my airbox and cut out the bottom of the filter then cout a hole on the bottom of the box and put a screen there, I also cut out the wall in the airbox and when i was done the poping cut in half. Then today i got my air injection delete in the mail and put that in and now there no pop at all. It sounds awsome, and its super loud... The best part is I have $31 dollors into the bike. oh and not to mention its 7 days old lol...
