I had the same headers on my 02 GT with a catted h-pipe. I had a tune done for these reasons (I also had it done to clean it up and run better and ended up making more power/torque):

I know you're going to have to shut off the rear most O2 sensors and shut of you MIL indicator.

Thanks Mustangwop Sounds better to do a tune then, considering for more power gains and for the o2 sensors. What kind of tune did you run?

For sure it'll run as is with em bolted on but tune will not only improve performance but adds to drive ability. BBKs headers typically fit very well on those cars / engines. Be sure to use factory studs / nuts and just as important, factory gaskets only.

I had it tuned locally in the GTA. If you want details on who did the tune and did an amazing job and who screwed it up many times and cost me a lot of money, PM me as I will not post that publicly.
