Thanks alot for your guys opinion!
vin's reply calms me down a little
would only use it for the test as i don't want to damage another cat. And the reason why the both stock cats broke is cause of the exhaust pop mod, i still want to run this one....
wondering if an obd2 check would be positiv too when i put a lambda spacer in between?
