im installing new headers, but under the factory manifold, below the heat shield, there is something. people have told me it could be a second cat which would mess up me puttin the headers on, ive heard its the resonator, ive heard flex pipe. its the thing between the downpipe and the gasket from the header. i was just wondering what exactly that part was.

As stated before, it should run the same as long as both O2 sensors are still there and intact. As I recall, installing a header on the 7A has decent returns. I know some members with a 5S put their original intake manifold back on for emissions testing but the 7A requires a little custom exhaust work since the header is too short and won't reach the factory exhaust under the car.
