I know on most cars, if you cut the Cat, you can expect a slight performance gain. It is pretty common practice up here, as we do not have emissions testings. I have been considering having this done as I suspect it is towards the end of it's life. <p>Will the Volvo start throwing codes and messing up if the cat gets gutted? If so, is there anyway around it?

Put a "cheater" on the rear O2 - a spacer sleeve that moves the rear O2 out of the main exhaust stream thereby altering the reading between front & rear O2's - and as a result, no CEL for cat.<p>IPD's Rallitek division sells it for about 30bucks.<p>It works - I pass NYS inspection (uses OBII readiness - no codes = pass)<p><br><IMG SRC="http://i27.photobucket.com/albums/c190/huseinholland/CarMods/XCV7020G0025.jpg" BORDER="0">img]

So that is all that is needed, to keep the car from giving a CEL?<br>That is not too bad then. I was half expecting to have to use a chip to pump the proper signal to the ECU.

Nope, just buy the spacer.
