That is interesting the "normal" code isn't the one that mine got.

Taking a look at the wiring (seen in the pic with the green mark) they seem to be to okay to me?

Praying that replacing the gaskets fixes my issues.

 

Just swapped out my gaskets. If anyone wants to see the OEM gaskets look below haha. Waiting for the sealant to dry and then going to clear the codes and cross my fingers.

Thanks all for the help so far. I'll let you know what happens!

 

So what gaskets did you end up using this time? It's really not recommended to use the oem on the invidia exhaust, which will eventually leak as shown in your pictures.

 

I ended up using the gaskets Sunny recommended above! The grimmspeed

 

Perfect I have those as well as a back up once my invidia gaskets leak again.Those are nice looking gaskets.

 

Update: one week in and no CEL.

Thanks again everyone.

 

Morning everyone! So reading the thread and buying he Grimmspeed gaskets AFTER getting the CEL light when I installed the Invidia exhaust. After installing the gaskets, the CEL went away for a few weeks. Well, today it's back. Should I replace the O2 sensors or try to just do the silicone gasket as 3ISRC said in his post? I'm just tired of these issues from replacing an exhaust on a car. I never had an issue putting an exhaust on any other sports car I've owned. Any advice is appreciated.

 

Here's more detailed information about gaskets and the Invidia exhaust. https://www.clublexus.com/forums/rc-...s-and-cel.html

 

I've done the Grimmspeed gaskets, the only thing left to do is the RTV sealant but is there ANYONE that has had success with this exhaust? Lexus says exhaust modifications should not be done on these cars. If it's a problem I'll put my stock exhaust back on. Just flipping ridiculous. Borla and every other exhaust there have not been issues with quality control.

 

Ever since I swapped to the Grimspeed gaskets replacing the OEM Lexus ones (that were clearly leaking by the looks of them) and put some RTV on it I've been good to go.

No codes or problems since 2021.

Believe many others have success with the Invidia as well.

 

that's a standard line from any oem, if you're going to follow what they say then obviously just leave the car stock. I've had that exhaust since 2019 and the thread I posted above has been helping new owners for years now.

 

Ok, I'll see about getting the RTV sealant on to see about fixing this. Does anyone know if the stock midpipe works with the Invidia axle back?
