if you do, be sure to have your Big-Boy Pants on... that place can get a little rough... particularly if you think even slightly outside the box, are new, and young.

I read that as well. I pulled my exhaust manifold off 6 months after getting my Spyder, at 130kmiles. Surprisingly the honeycomb was 100% perfect and in tact, but I chipped it out per the advice. It was burning some oil at the time, and has only gotten worse with wear. In my case, the pre-cats had no effect on my engine wear. But even with that, it still passes a SF Bay Area rolling dyno emissions test. For now at least.

I agree. Good luck!
