Hi, i fitted my turbo xs type h rfl today it does sound loud but u gotta drive it hard to get a loud like at 5k rpm, it has a adjustable top think when u screw it rite in makes it a lil quieter ,has any 1 got this dump valve and how many turns do i do from screwed rite in to get the perfect sound? its a very fast psssshhhhhh but when at 2.5-3.5 it sounds nice but not loud, any suggestions?? everything was fitted accordingly

 

Also r u supposed to screw it rite in or rite out?

 

Any 1 ???
