The best advice that can be given is to invest in an OBDII Scanner like the Scangauge II or an ELMScan unit and software for your laptop or PC.
These devices allow you to read and clear trouble codes off the ECU, which is what triggers the ABS, VSC, and TRAC lights to come on when you experience a fault.
From what you are describing, it is very possible that you have a failed MAF, but it is always best to check the codes to make sure before you go spending $$$ on a new MAF sensor. Typically, the trouble codes will tell you the fault, which gives you a very specific idea of what may be wrong. It's easier, less time-consuming, and MUCH cheaper than just replacing sensors and hoping for the best. Sensors are expensive and add up fast.
Beyond that, unless your SRI and header can be proven to be the source of your failure, most dealerships will ignore these additions. Unfortunately, with the MAF, the SRI is more than likely going to be pointed at as the culprit in this situation.
Good luck!

Ouch!
Do you know anyone that might have an OBDII scanner? If not, most auto parts stores such as O'Reiley or AutoZone may be willing to scan you for free if you can get the car up there.
That would be the best place to start. It is where the dealership would start, as well. It would at least give you an idea of what is wrong, even if you have to take it to the dealership for repairs. This gives you some defense if their tech department does attempt to put the blame on the performance parts.
How long ago did you add the header and SRI? Is there anything that you have done recently to the xB, any recent major change that you can think of?

i think a failed cat or a oxygen sensor going bad causes that to show up on the dash
