so i have the Dinan diff which means at like 3600-4000 rpm i am going highway speeds, say 78 mph. i just recently removed my MPE because in that specific range, there is some pressure in the pipes and a tremendous drone in the car that i just could not take. my question is do you guys think that this would be the case for EVERY exhaust i get in this range?

keep in mind i am going for something slightly louder than my OEM set up, but nothign crazy like gintani or such. i was wondering if the dinan x pipe with stock muffler was crazy. hard part is that drone (or maybe not drone but whatever it is) right in that specific range.

thanks guys
