I did some poking around tonight; Push the adjustable pipe all the way in and all the way out. Drone was worse with pipe pushed in. I ended up pulling out the pipes all the way out which is about 2.5" from the bumper cut out. Little more than my liking but can't stand the drone around 2k rpm. I may also try to drop the exhaust a bit more down. Right now, it's about 3/4" all around from the opening.
