If you buy the ebay headers, to solve the O2 sensor problem, just purchase a post-cat 02 sensor for a 95 ST. They fit perfectly as a pre-cat O2 for these headers. Only problem I had was finding those damn self-locking nuts to secure it (eventually went to a Toyota dealer to get them b/c Home Depot/Ace Hardware don't have them).
Umm...the exact item I purchased was a Bosch Universal O2 sensor, product number is 12210 at Autozone.

i bought the same header are stock header has an o2 sensor in the front then thier another one on the flex pipe...the ebay header only has 1 o2 sensor and its just on the header not one the flex pipe...what i did was went to an exhaust shop and they cut of tht lil piece from my stock flex pipe with the o2 sensor and weld it on to the ebay flex pipe...also the header doesnt reach all the way to the cat so what i did was buy a 93 ford probe cat which is longer...but tht was just me now i cnt pass state emmision i hvae to pay for it now but its worth it its onli $95 every 2 or 3 years.
