Differing opinions on that. Maybe 5hp by itself. 10 if you match a good muffler to it? There are those that claim 10hp with a cat delete, but I think that may only hold true with MAJOR mods. You can get close with the right performance cat, so for that reason, it'* worth keeping.
I don't want to get caught without one, and I'd like my exhaust to be worked on by a pro, which wouldn't be possible if I had deleted the cat.

I'll go with that. The routing and components in the 2000+ SSEi'* just LOOKS less restrictive. I know alot of guys are running in the 13'* with stock exhaust.
I think GM paid alot more attention to the exhaust post-99.
The difference between a stock cat and a performance unit is less than 10% when measuring CFM'*.

Simply put, if an L67 can't outflow one, you'll be ok with the 2.5", as long as it'* a performance unit
The extra price of a 3" with adapters probably wouldn't be worth it for the returns in performance.

This is exactly what my Cherry Bomb glasspack looks like inside..."perforated"...and the reason I chose it to preceed my MagnaFlow stainless muffler. Cool.
Now that I know what the MagnaFlow looks like, if I need to replace the Cherry Bomb, I've got a confirmed visual that it is virtually identical, except the body is stainless steel. Excellent. :P
Thanks, Will.
