Hi all. I'm kinda new to this forum. Just got my 96 St Coupe a couple of weeks ago. Traded my 99 Solara for it....and $3000
 Anyway, I am orderin up parts and I wondered if anybody with OBD2 has installed a high-flow cat. If so, does it affect the rear O2 sensor and set the cel? I ordered a corolla high-flow and according to the toyota part numbers, the st and corolla 7afe share the same cat so hopefully it will be a direct bolt on. Let me know if anybody has any info. Thanks. |

Got the cat yesterday and installed it. 4 bolts. Pretty easy, except getting the old rusty ones out laying on my back in the garage. It seems to breathe a bit better but I really need to get a more high flow muffler. Does it make a difference if I just get a muffler or is it better to get a complete cat back?
