Default twe headers questions

I was looking all over the twe website to see if these headers below maintain the stock cat. Does anyone know? Also, are these equal length also?

NEW Header (4-2-1 High Output)
(Fits automatic transmissions) 25-421-hdr-HO
NEW Header (4-2-1 Super Sport)
(Fits automatic transmissions) 25-421-hdr-SS

What year do you have. If you have any RS from 98-05, then yes, the TWE header will bolt up to the stock cat. The TWE header is the only eq header that ends in the stock location. If you have a new 06, I'm not even sure if it will fit. The new 06 has an eq header from the factory, so who knows where the header ends, and the cat section begins.
