I read the Greddy SP Cat-Back Exhaust Installation guide here, and was wondering if there is an O2 sensor for the 1997 GT models that will require me to weild my exhaust OR is there a way to bypass the sensor? Has anyone here install the Greddy Exhaust on their GT and could help me out? Thanks.

One bung? Well if it has the extra sensor, I heard you could bypass it, has anyone done this?

I have a 97 ST with a GReddy and soon I'm going to connect a resistor to the sensor that's after the caddy. That will turn off the check engine light and you really don't need that sensor as long as you have one that's before the caddy. My buddy's a mechanic and he's gonna do it for me. I'll keep you posted.
Has anybody put a greddy sp exhaust on a 1999 celica yet?
Did this mod today, and there is NO O2 sensor on the 1997 GT models.
He is right, there is no O2 sensor on 96-98 5S-FE

dont you mean no sensor after the 2nd converter/flex pipe? My 97GT has 2 oxygen sensors, both are on the downpipe on the front side of the motor, 1 before and 1 after the 1st converter, well before the flex pipe and 2nd converter. If I understand things right, the Greddy only comes up to the rear of the 2nd catalytic converter...thus "cat-back" system,,,,,
