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.

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.

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!!!!
