Excellent explanation, besides that I used my humble scanner and I was able to check: cylinder misfire (6) ok , O2 sensor (4) ok , catalytic 2 ok, catalytic 1 HIGH , max value 3000, reading 3239 , code P0420 , I’m going to try cleaning first before replacing it. Vehicle mileage 140k , my wife bought it brand new this’s the first problem in this vehicle, ‘13 Acura RDX

Would u recommend universal catalytic converters, welded to replace in the old ones?i meant cutting the old one from the assembly and weld on the universal ones? Thank u

awesome video! My 2007 acura tl is smoking from the forward portion of the catalytic converter that connects to the exhaust. could is possible be clogged, maybe an o-ring breaking down ?

My 2014 Ford Mustang v6 3.7 is quiet and does not seem to have the listed rating of 305 HP. I am wondering if it can be the catalytic converters. The car drives so quiet. Any ideas? No codes at all. Is there an additive to put in the gas? Thank you.
