Well, at the end of Christine he rams the car with a Caterpillar and drops the bucket on it … maybe hard to explain to the insurance company, but if it’s enough of a problem…

I hadn’t used the remflex gaskets you recommend when the shop was installing the exhaust
I got a CEL just 2 days after install and had it taken to a mechanic I know
I explained how I just got an exhaust installed so he had an idea of what could be wrong
Ended up being the rear 02 sensor (behind the cats)
he asked me if I felt any difference driving or in power and I still haven’t
he turned it off and said not to worry about it
should I get the gaskets installed? I fear that this might be exhaust leak
Speech over, help needed, thank you

I have about 4000 miles on my 2019 RC F since I got the Lexus dealer to use the Remflex gaskets along with the high temp silicone gasket sealer. No longer have the check engine light (CEL) issue. But next year I'm going to do something about the noise level. While it sounds good when you're on it, I don't drive like that much any more. Mainly mergign with traffic on the freeway. Not very enjoyable with the loud noise around town or on the turn pike. Probably going to look at some 3" mufflers and put back in where the resonators were eliminated when the Invidia system was added.
And I agree with Civib2 in that I'd try to find out why the CEL is coming on. Clearly looks like there's still and exhaust leak. As far as I know there are 2 O2 sensors on each side...one before and one after the cats? Anyone know if that's correct?

Just did this install this weekend and I am extremely happy with the results. I used all the parts you recommended and everything went together super easy. The car sounds so much better and doesn't drone at all. Thanks for the writeup!
