Can I remove the catalytic converter on my 08 XC70?

[REnglerth]

Not to my knowledge. I bought it used at 85,000; it now has 97,500.

Spacers don't fit the problem they just hide the problem from the ECM.

Sounds like a Sewing machine ... get a Mechanics Stethoscope and pinpoint the ticking, starting with, but not ending with, the fuel injectors.

[REnglerth]

What I meant is it runs smooth, no ticking. Your responses have be immensely helpful and I thank you!

that car has two catalysts integral with the two exhaust manifolds plus another pair aft of the rear o2 sensors. it is almost impossible that both front cats failed at one time.
Besides p0430 and p0420 for cat efficiency what are the other two codes?

[REnglerth]

I had made a mistake, it was only those two codes.
