should i replace catalytic convertor in my 2005 lexus 350 rx?
If you like the vehicle why not repair it and keep it. You might be able to save a few bucks on catalyst replacement by pricing this repair at a local exhaust or repair shop other than the Lexus dealership.
I agree with Bob, but how do you know the cat is faulty or clogged?
Or put better fuel .see what that does.
