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.

 

yeah that is why i did not want to buy an offroad H till i bought a tuner, i had a bad experience with MIL's on my '00 V6 (made a full custom dual exhuast and the MIL's did not work for sht)

 

The MILs should work just fine if you install them correctly... unless you bought them from e-Bay

 

I purchased the BBK brand. Looks well built.

 

I never would have purchased them if i knew they didn't work. I guess I will go to the muffler shop and if that doesn't work i guess it is time for a tuner.
