have a local muffler shop, a private owner place- ask for a cat and muffler inspection
Its usually free- they do a pressure and flow test to see whats needed, if anything They have to document the reason for cat replacement to the govt- and these test must be included with the paperwork Those guys know exhaust problems and can offer good advice If you need do need a cat- our vendor Excelerate has standard and hi performace cats, the good one costing only 300, dealer wants 1000! You could just need an O2 sensor, or maybe just the EGR ports are plugged and need to be cleaned- that will throw a low flow code too Codes are NOT diagnosis~ they are CLUES!!!!! remind us what year and current mileage- clean title?- not salvage/rebuilt car right? |
if you get a hi flow cat like a RT Cat get a spark plug non fouler 'cus you'll need it. I actually had to use two to stop getting the P0420 codes and I replaced my 02 sensor in the process of the heater circuit fried.
