Well, that's the good news. The dealer screwed up. IMHO, you want to keep the headers. What exhaust is installed, I assume it's a third part dual system since both sets of cats are gone. Probably a JoeZ or Borla. Try to keep that. Have the dealer weld in a set of HiFlow cats and as JoeZ suggested above, realign the headers. That is, unless you want to return it to stock. As has been suggested, if you do this you'll lose about 50 wheel horsepower.
Try to ignore ROK, he believes no modifications should ever be performed on an ISF, and I assume any car. But, that is his opinion, not the opinion of 99% of forum members.

How is having headers relevant to tuning? The ECU compensates enough to make headers worthwhile. Sure it is difficult to install almost all headers are fairly difficult to install on all makes/models but you have to pay to play to get to that 400whp goal.

You can tune the check of the rear 02 sensors out, so no check engine light. There is no worrying that the box will go bad, or if one of the wires will hit the header and burn and short out.
Needless to say, as I've gotten older I've learned to just buy something fast right out of the box and enjoy it and beat the **** out of it.

You dont have to play with wires or wire in a black box sensor.

BTW, modding cars always poses issues.. if you're worried about CEL's, noises, things that can go wrong from any aftermarket mod then I agree, just buy a stock car and leave it alone.
(This is why I'm willing to pay more to go to a reputable shop with experience on IS-F installs and get it done right the first time and not have the problems the OP is having)

I got new set of tires, same size as before, running front 245/35/19 on 2010 stock wheels with 10mm spacers, sitting low on KW coilovers. Now, unfortunately, I am getting some front passenger side rubbing against the fender liner. I will raise the coils by two turns likely to made up for the fresh new tires increased size. I only rub when turning left, I wonder if extending the length of my right adjustable sway bar link would help to reduce the body roll when turning left and help the situation?
