I got an 04' 6.0L with a 4" MBRP exhaust. I have a drone/noise in the exhaust, seems like around the turbo area at exactly 1100RPM +/-. It will do it while driving and in neutral in the driveway. I have done a little research and it seems that it could be a couple of things.
-exhaust alignment (downpipe between CAT and turbo)
-turbo pedestal (A-brace needed) or new pedestal
Note the truck has 110,000 on it and had never had any noise up until I just recently deleted my EGR cooler. Which makes sense because I removed all my y-pipe connections etc.
What do you guys think?
