Howdy,when I get over 20lbs of boost I can hear the tubing rattle even under the dash.what can I do to fix this,I am leaving next week for a 2500 mile trip to Idaho with my 5er and don't want to listen to this the whole trip.

 

mine does it when the exhaust brake is on and i have alot of backpressure built slowing down. i see you have a jacobs on it,
