Default to cat or not to cat

I know environmentally friendly is the way to go but hp wise that blows. Would I be better off getting a hi-flow cat or just a straight pipe with some "fake" cats? Anyone have input/experience?

I doubt you will notice much if any difference between just one highflow cat and no cats at all. So get the high flow cat and save some trees.

Default Vrooom...

Well, I have a hard time justifying to myself running catless, as its just kinda filthy. You can pull about 10hp out of doing a high flow cat conversion. I have no idea how much more you can get out of going catless. I cant imagine that it would free up so much more as to be worth putting up with the stinky exhaust of a catless setup. Just my 2 cents..
