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.

from what i can tell the 94-95 ST had TWO cat's, primary in the manifold, and secondary is located down stream.. (non cali-spec[my original setup]), and the 96+ST had ONE cat, down stream of the manifold (under the car) (non-cali spec)
With the changes in 96 (OBDII) with sequential injection, and better emisions control. looks like that they did not need to have a primary cat in the manifold (again, not sure about the cali-spec).. at least that is from what i have been able to gather. -------------------- |
