If out of warranty,WALKER brand is good for replacement, skip the well known high advertised brands, higher price does not equate to better.
Pros: good for replacement
Cons: higher price not better

The only real issue I’ve had is a failed cat converter at about 1000 miles, must have just been a bad one from the factory. Fully covered under warranty anyway.
Pros: dream to drive and own
Cons: failed cat converter
Mileage: 1000 km
Catalysts are another one, I can’t buy magnaflow/walker cats that reasonable anywhere local, I’ll wait if the customer is good with it for the savings.
Pros: reasonable price, customer savings
If you checked the plugs and coils it's likely to be a clogged catalytic converter. The age of the car is right for this. This happened to me on my 2001 a few years back.
Cons: clogged catalytic converter
Vehicle:
Subaru
Went through a new cat and new AC compressor around 200k.

I had a 2019 Kia Rio S bought new. It was a spunky little car that I could get about 40 mph on. Had no issues with it until it hit about 5 years old at about 80k miles with an engine misfire. Took it to my mechanic and they couldn't get it to happen again. A few thousand miles later, catalytic converter started going bad.
Pros: spunky little car
Cons: engine misfire, catalytic converter
Vehicle:
Kia Rio
Mileage: 128748 km

Cons: catalytic converter repair
Vehicle:
Ford Explorer
Mileage: 220000 km
Replaced original manifold cat last December with OE Kia--that cost about $2200 doing it myself. After 5K miles I was getting a pending P0420. Endoscope showed cat inlet center section bubbling...looking like melting had started.
Cons: P0420 code, melting started
Vehicle:
Kia Soul
Mileage: 5000 km
Around August 12th my son was driving my vehicle and my motor blew!! I was truly lucky they were able to to get Kia to replace motor but the damage was already done to my catalytic converter so they said I had to replace that!
Pros: motor replaced by Kia
Cons: catalytic converter damaged
The vehicle started losing acceleration power so we took it in and was told the catalytic converter was bad and needed to be replaced at a total cost of $4,500. I explained to the service manager that the vehicle began consuming excessive amounts of oil. I explained that the vehicle was serviced by them and that I wasn’t paying that amount for a catalytic converter just for it to fail again due to a more deeper issue with the engine.
Cons: catalytic converter failed, expensive repair, oil consumption
Vehicle:
Hyundai Tucson
