Default LT Headers and stock cats

Hello all,
I have been planning on getting long tube headers in the near future...however I need to be as economical as possible. My question is this....could I still get the typical 25-30 HP with long tube headers and tuning and keep the stock catalytic converters? Most people say that removing the cats or going to high-flow versions will only bring you 5-8 HP. Is this all I'm giving up if I keep the stock cats with LTs? I could always add high-flow cats in the future and get it re-tuned as I know someone who tunes cars (i.e., no extra cost for tuning). Sound is not a big deal to me (in fact, less is better as my car is a daily driver), I just want more power! Anyway, let me know your thoughts. Thanks.

Josh

Saw real world testing on this issue and removing the cats only gained 5 HP, not worth going without in my opinion. Dealing with the laws on this issue are not worth it.
