    OK. Tchnically you're right. You CAN reuse them, but you have to cut, reweld, and redo them, to make them work with headers. Aftermarket high flows still flow better and don't require any manipulation. The factory cats are crap, and GM has sent out letters about their failures. I don't suggest using them.

    Well, a smaller pipe diameter will increase air speed at low rpm which will effiiciently evacuate the chamber at low speeds, helping low speed torque. BUT, the smaller pipes become a restriction at higher engine speeds.

    About collector length, adding 8 to 10 inchs of collector length can boost low-end torque. But thats for open header, drag strip applications. Adding a large diameter H pipe before the mufflers usually increases torque at or below peak torque while not detracting from top end horsepower. This is similar to adding collector length. Thats all I can remember.

    So long as you do not have to pass any emissions testing, yes. Another option is high flow cats and long tubes, subject to local emissions testing. If you need to pass emissions, it would depend on what type of testing they do in your area. If they do visual testing, moving the cats can cause you to fail. You cannot move cats from their factory placement and be legal.

    Yeah! I just went to smog my car today, and what's the first thing they BEFORE hooking up their stuff to my car? They squeezed under my car with a flashlight and inspected my stock tubes. Fortunately, the guy didn't hassle me about my JBA headers. What a bunch of crap!!!!
