Somewhere in it's life my 03 had it's exhaust hit by a curb closing the gap between the 02 sensors and engine blocks and axles. As a result it doesn't take much of a bump or tap to break the sensors. Any ideas short of buying a new header etc.?

only thing i can think of is block off the hole that the o2 fits in now and have another bung welded in where it wont hit anything but the right way is to buy a new or a good used header

Maybe buy a hfc with side mounted O2 sensor bungs, might work, but fixing the problem will probably be the best solution.

Your best bet is to get a new header, with you being in CA I don't think you have any other options besides the stock cat.

Most aftermarket cats arent CARB legal. The CFM HFC is 49 state legal, it looks like CFM is coming out with a 50 state HFC sometime soon.

The same thing happened to my header except a bit worse. I couldn't even get the O2 senors into the cat when I bumped mine.

Get a new header. A lot of us have gone through the bent/broken 02 thing. Nature of the beast. Just keep the tires on the street in the future and it shouldn't happen
