I have a 2012 Ram Express 2WD SBSC. I am considering putting a Pypes M80 and Magnaflow Y-Pipe or Mufflex DOD18M kit on my truck. The Pypes setup will be unique and cheaper but require welding. I really don't want to weld on my brand new truck. I figure dodge doesn't like that either. :4-dontknow: My question is will welding the exhaust negatively effect the PCM or any sensors? I've had many of my vehicle's exhaust system welded with no problems. I like the DOD18M kit because it's bolt-in. Thanks for any help guys.
