Hey guys I have a 95Z28 A4 California model (twin cat). For the looks of it my Y pipe is so dam closed to the sensor itself and I wonder if I am going to have to drop the whole darn thing. Has anyone been able to remove the sensor without going through all the trouble?

Those exhaust bolts look rusted... they have never been removed. I dread doing all that work if it can be avoided.

Bump to the tap

anyone?

 

Dont know about the twin cat, but when i went to loosen the exhuast bolts when i changed the oil pan gasket they broke. BE CAREFULL!!

 

You'll definately have to drop that y-pipe for the sensor especially once you see how long it is. And you could always try PB blasting those bolts it should help.

 

DANG DANG DANG!!! Thats what I was afraid of. I dont know if you guys seen the Y pipe on this car... I think it goes all the way back to the muffler!!!

I was underneath her and I didnt see any connection from the Cats all the way back.. I dont know if it even has one at the rear by the tires or not..

Oh well.

Yep, don't try it. I did and broke the tip of the old one off in the pan. Hmmmmm. I wonder if that has anything to do with the motor going???
