Which would be quieter? I currently have offroad X, stock resonators and OTA's and Magnaflow Race Series (muffler deletes) on a twin turbo coyote. It's just a LITTLE louder than I'd like with some drone in the 2-2200 rpm range. Would welding an inline muffler like a Pypes M-80 or Magnaflow Competition in place of the resonators make it MORE or LESS quiet?
