I think that any cat that fits in the space provided will work. I guess the unknown is will you still get a CEL from the downstream O2 sensor. Post pics if you can, I am interested in the result. I may do something similar when mine rusts out. Make sure he gets the flex joint in the y-pipe close to where the stock flex joint is. I have a few issues with my exhaust set up being too rigid.
