P0159 P0139 After H-Pipe Install
I installed the Pypes H-Pipe and MIL eliminators and now I have both codes. I checked for exhaust leaks and can't find any. Maybe the MILS aren't working. Any help would be appreciated.

Those codes are for both rear o2 sensors. Those mils aren't doing there job. Just buy a cai/tuner and have them set the tune up for o/r h-pipe as well, they will turn the rear o2's off in the tune and you want have any more problems. You're not the first to use mils and they didn't work properly.
