if u remove the cats w/out a tune u will get a check engine light related to the rear o2 sensors. i would just wait for the tuner. i ran mine w/out the tuner and got check engine light and felt a slight loss of power, but once i loaded the tune w/ O2 sensors off, it was fine.

I am running the pypes o/r h and stingers. I actually got a cel when I switched out the axlebacks after a few runs. Don't worry about having a tuner ready. Just go out and switch and do the tuner when it gets there. No big deal. Are you going to install yourself? I did mine and fitment was terrible, just took my time and installed myself. Your adding a side exhaust? Just be careful when you switch over the o2 sensors from the stock h to the pypes. Just unplug the o2s and bring down the factory h to the ground move them over to the new pypes. try not to bend or twist the wires on the 02s.
