It should work, but I don't know about that manufacturer.... I ordered a similar header, but it was a T1R, and I had to wait 3-4 months for it to arrive, check out to see if they have them in stock first. My T1R needed a few modifications to fit perfectly (had to bend EGR pipe to align with the connection, and the lower bracket that attaches to the down pipe had a third mounting/bolt hole that mounts to the engine block, and that had to be modified to fit too.) Let us know how it works out if you get it--the prices of the OEM replacement is scary!
Yeah, I sold my T1R to another guy on the forum because he had to replace his cat too.... I will get another header if/when I need to replace mine in the future, but it won't sound like a Hybrid any more, LOL!
Well, tell them you got a P0420 DTC, but the troubleshooting starts with possibility of poor quality fuel, then ruling that out; next step to replace the cat to see if the that resolves the problem.... There are more steps to that, but basically sums it up; funny how they go quite quickly to replacing the most expensive part in troubleshooting.
Litz, you have the factory manual with the troubleshooting process. I do not. My point was the code does not universally refer to a bad part. It refers to a particular process. Many think there is a 1 to 1 relationship between the code and which part to replace. There isn’t.
