Just get a catted X/H pipe. They're not expensive. By the time you get two high flow cats and have them spliced in you're at the cost of buying an x/h pipe and doing it yourself.
edit: Nevermind, looks like prices went up and seems to be hard to find any catted h pipes. Most exhaust shops will not remove cats from a car or they face a huge fine per Federal law . If you find one that will, just get some SLP cats and have them spliced in.
