What's the difference (if any) in H/P when using cats vs. race pipes. Thanks

I think most folks will tell you it might be between 5-7 hp. I have hit the track with them on and off and didn't really notice a difference in my mph or ET's.

It does sound more bad-*** with the orp's on though but through the corsa it is a bit raspy (and I have vibration/rattling issues)

I'm just about to put the orp's back on since my inspection isn't for about 6 months.

Thats cool, I want to keep the cats on so it's not as loud, neighbors complained when i had my hookers on. heh
