I'm thinking about getting 2.5in duals with an H pipe and a couple glasspacks in under my truck. I'm not worries about the rear o2's because I'm just gonna tune those out. My question is, does the exhaust shop just add bungs for the front o2 sensors? I thought those are the ones that affect A/F ratio. I just want to make sure so nothing is getting f'ed up by the time the system gets done and installed. Appreciate the help
