As Derek says in the above post..... If you want to test the noise for your self just disconnect the suction tube from the Trottle body and start and rev the eng. Get the revs up high so you can hear that but also at a highway RPM to see if you can handle it. That's about what it will sound like but not quit as loud because it will be going through a filter and tubing. It will give you a idea though. Be warned if you do this I think you'll like what you hear.
