Greetings all:
I have my 2007 CS in the shop today due to CEL and it looks like I have 2 bad O2 sensors - as well as >2.5 PSI back pressure in the catalytic converters. Mechanic says that is somewhat high and may indicate the Cat is bad. Hopefully the new sensors will fix the CEL problem, but if not, can someone recommend good high flow replacement Cat Converter? I track the car aggressively with race exhaust and other upgrades, so improving flow int eh Cats would be nice.
Thanks in advance.
