The Kizashi catalytic converter part number seems to be 14190-57L11 and I've found one online but it's incredibly expensive.
megazip.net is listing a less expensive alternative: 14190-57L00-H02 "PIPE,EXH NO.1, Germany,SEE NOTE" (but there's no note I can see)?
Is anyone familiar with this other part? I can't seem to find reference to it anywhere else so I'm suspicious that it could be a mistake, or that the note I can't see might list some limitations.
Catalytic converter part #?
What is the reason for replacing this catalytic converter. If it's for it being cracked, you can certainly repair it by welding it. If it's putting out a code of PO 420 this is best addressed by welding, an O2 bung back behind the second catalytic converter and lengthening the O2 sensor wires by 3 foot and moving that sensor back. This puts two aged Catalytic converter's to work where one used to do the job. This works perfectly. There are alternatives because of this catalytic converter being so expensive and that is aftermarket. If you can find it listed for the Kizashi you probably can find it listed for the 2010 SX 42 L, and this would be the same front cat, which is integrated into exhaust manifold.

Wow yeah cool idea! Thanks for the reply
In my case, the issue is it's cracked, no problems with codes (yet.) The best the guy who looked at it could do is apply some muffler paste and buy me some time so I've started fishing around for a replacement. I don't recall him offering to do a weld so maybe I'll try another place that I know for sure can do that and see what they think.

There are 3 reasons for this manifold to crack. 1) Improper stress on exhaust like to small of a replacement flex section and or bent exhaust. 2) Missing stiffener bracket from oil pan to bottom of manifold. This is very important. 3) The manifold naturally warps from the high heat. When these are welded, I bolt the manifold to the side of my work bench with a hacksaw blade pinched in the center to over compensate for warpage and then mig weld cracks then let it cool before unbolting.ibkev wrote: ↑Wed May 14, 2025 4:50 pm Wow yeah cool idea!
