I have a bit of a problem I was hoping to get some guidance on.

My car had a P0420 check engine light. I researched this and found that it was generally the catalytic converter. So, I went out and bought a used exhaust manifold\cat for $150.

I am an amateur but I followed the DIY guide and it took me about 3-4 hours with a few trips to buy tools to get the thing replaced. Everything on the car is running great now... the check engine light is gone and no problems... except the heat shield does not fit anymore.

Apparently on the replacement manifold I received the exhaust pipes are bent differently, and now my old heat shield won't fit on. Pipes 1 and 2 bend off to the left, but then pipes 3&4 rise up preventing my old heat shield from bolting on. The exhaust had to come from a similar 2FAZE engined car... everything else fit perfectly.

My car is a 2006 tC. I have included a picture... can anyone point me in the right direction as to which heat shield I would need? Any help is greatly appreciated

 

Try an 08 shield.

 

I did some research on this and I think you are right... It looks like the heat shield may have been redesigned around 05/2006.

I had a heck of a time getting my heat shield off because the o2 sensor was preventing it from coming out... I am guessing they redesigned it to make it easier to work on.

 

Mystery solved... it was part number 171670H040.. from a 2008 scion tc. I got the part in today and it fits perfectly over the manifold. They changed the design on the heatshield so that it does not go over the o2 sensor... making it much easier to take off the shield or the sensor.

Now my check engine light is gone and all is well.

Thanks for the help.
