When I get my xA Im going to do a full custom exhaust. I was wondering how many O2 sensors does the xA have? I know the tC has 3, but from the pics I have seen of the under side of a xA it looks like only 1. Also I have another question.

Is that little part I have pictured the cat on this car? Thanks option wagon for the pic. Thanks for any help & im sorry but I searched for O2 Sensor & Cat. O2 Sensor gave me nothing & Cat give me 14 answers, but I was only looking in the xA section :oops: so im sorry if this has been asked.

I believe it has 2. Technically the first one is an Air/Fuel Sensor and the one right after the car is an O2 sensor that is just there to make sure the cat is working right.

OK that helps, thanks. So then 1 is mounted on the header & the other by the cat. So that makes finding a cat much cheaper because at first I was looking into a cat that had 2 O2 bungs. :oops:

You really haven't seen the precisionmuffler.com manifold back system? It is made for the xA and the xB.

by the way there are two 02 Sensors on the exhaust. One before the cat and after, NOT on the manifold. :D

That does look good. The main thing is that cost. $465 :shock:. The parts Im going to use for my exhaust total $135, So I would think I could get all the pipe between for $330. Also thanks for clearing up the place of the bungs. That pic I saw only had that 1 that I could see.

Toyota did a dumb thing incorporating the cat into the rest of the exhaust. They should have made it like Civics are where the cat can be unbolted at it's own flanges.
