under drive pullies no but the o/r h pipe you may need the rear o2 sensors turned off to stop the check engine light from coming on

you won't need a whole new tune, but you'll have to go into your tune to turn off the rear O2 sensors. or you could just buy the MIL eliminators. but if you already have the tuner, save some cash and use the tuner to turn them off...

After I got my o/r h-pipe, I e-mailed Brenspeed and they said they had already turned the sensors off in my first tune.

My CEL came on even though I turned them off with my tuner. Called up Bama and he told me that the tuner wouldnt do it on a small percentage of them. So he sent me a new tune, no more CEL
