- i think is Less low end torque if your not putting out enough hp. Just like having too big of exhaust. Anyone?

If you're n/a, gutting the cat will probably improve your high end flow a little, but you'll lose a little torque in the low to mid rpm's.
If you're turbo'd, then the gutted cat will allow the turbo to spool up a little quicker. Gutting the cat-converter is a cheaper alternative to a straight pipe; however, a gutted cat isn't as good as a test-pipe.
A gutted cat is like a "cooling" chamber when compared to a straight pipe. A test pipe is a little better because it has a smaller diameter, thus keeping the exhaust heat hot, and hot air travels faster than cooler air.
