DP install questions (help needed)
I was about to install the Downpipe from an 2.0 SS on my 2.2 I noticed that my 2.2 has two O2 sensors and the DP from the 2.0 only has one. Also the 2.2 has two cats. Can I install the 2.0 dp if so what do you do with the second O2 sensor?

the 2nd o2 sensor on non air injection cars is on the manifold. on air injection cars there's 2 on the downpipe. only way to fix it is to tap the pipe and have a bung welded in.

You mean SAI? I dont think I have that here are some pics of my Engine.
I realized I need to install the 2.0 header and downpipe together so I have a place for both O2 sensors to plug in. The 2.0 header has a place to screw in the O2 sensor while the 2.2 plugs the the O2 sensor in the top of the down pipe. Its still wierd to have the 2 cats though.

the DP wont work w/out a LSJ header, ur mdoel cobalt came with the 02's in the dp, the other cobalts have 1 sensor in the header, the other in the dp, and u just happend to be a model with it in the dp, so u need a lsj header, btw i have 2 of them sitting in my garage right now
