I went and got headers and test pipes to go with the new engine. Worth a shot?

Interesting, I would think that going too lean (increase in heat) would cause the cats to go. I have a lift at home, so i'll put it up this weekend and check the cats. I used to have HFCs and I blew through those. I put stock cats on and has only been 1K miles tops on them with the S.C. Cats have 50K miles on them. I have been planning on using some testpipes and welding on some Cats from a v8 or something.
