thanks, I just talked to a shady tuning shop and they told me the best idea would be to drop the whole thing and gut them

On another note, you can try these MaganFlow CATS, they are CARB compliant: https://www.magnaflow.com/collection...alifornia=true

Nope, love our weather way too much. I've traveled all over the US, and each state has its own charm, but none like Cali. Only thing I hate here is some of our liberalism, but weather trumps all. Where else can you wear shorts and go to the beach all year round (I was just at Newport Beach last week)? And Cali women. Damn.

Make sure they are from a RWD IS250.
Fitment is the same for all of them, though there are several different part numbers depending on year.

I use
And bought a $7 OBDII 1' cable extension for hard to reach connectors. A few members in 1Addicts (BMW) recommended it, if it works for them and those cars are gremlins, it sure worked for the Lexus.
