Might sound stupid but it worked for me on each car the 5+ years I had them but it's worth a shot regardless, as it will have to be done one way or the other.
However, A lot of experienced/knowledgeable guys on here will tell you that having no cat doesn't yield any substantial gains over having a high-flow cat for street driving/moderate HP applications.
That little trick has to take some of the fun out of an on ramp, but may very well be worth it if it saves the effort of a swap. Although the additional cost of high-flow catted is understood, weighing that makes me think a swap every couple years isn't so horrible.
