Most power out of a cat-back system for a 97

Does anyone know which aftermarket cat-back system provides the greatest power increases? Really the only new ones I can find are from Gibson and LC Engineering. I know that there must be others out there but how do they compare? Right now my exhaust is broken right after the cat, so the way the new system sounds isn't a big concern because anything will be better. I want performance more than sound.

 

You aren't going to get a noticeable power increase from any cat-back system over stock. It just sounds like you do. I have never seen anybody, who wasn't selling one, produce any tested numbers to indicate a power increase. Just a lot of folks who say, "I got a lot more power!" or "I felt more power in the upper rpm range." In reality, it sounds more powerful, but it isn't. They are a lot less expensive than replacement with oem stuff, so pick the one that has the sound you want and go with it.
