Hello once again Volvo enthusiasts.
Newbie exhaust question here (I just got done searching through threads for an hour and I can't find an answer).
-Will purchasing an off the rack muffler from Magnaflow or Flowmaster affect the car's ECU or overall (longterm) operation? Note: I'm just looking for a louder, deeper tone. Not looking to squeeze out extra HP with larger pipes and a new cat or anything like that.
Thanks for the input!
