Magnaflow vs OEM Catalytic Converters

My catalytic converters AND TRD exhaust were stolen in May 2021 and my 2011 Tundra CM has been in the shop since then. I got a call today from shop and they don't have a delivery date of the OEM cats until possibly August some time. They offered to order me Magnaflow OEM grade cats that can have the truck back on the road by end next week.

My questions are, should I go with the Magnaflows? or wait for the OEMs to come in? Do I need to worry that the Magnaflows will cause a CEL to come on? or should they be fine?

 

anybody have an idea?

 

Hello,
I would call Keith Carty of Dirty Deeds Industries and pick his brain. No one knows Tundra's like Keith does. He is out of the office most days, but is always available via phone. You can call or text him anytime at 760-877-4234. He does take many calls and texts a day, but is very good at getting back to everyone.

Thanks, Shawna, DDI

 

Ask them specifically: what Magnaflow part numbers would they be installing? If it comes back on the Magnaflow site as the OEM grade direct fit it's a solid replacement. Should be no issues.

 

Did you go with the MagnaFlow?

 

There are a couple threads on this subject, so I am going to post this a more than once.
I had my passenger side cats stolen. I have insurance so the cost was not the issue. Getting cats was.
Since I was unable to get OEM, I bought MagnaFlow. There is a HM (heavy metal) version. I did NOT get that one. Bought the Magnaflow #49630
I used the old O2 sensor next to the exhaust manifold (I think it is also called upstream). Bought the lower O2 sensor (down stream? The one in between the cats.) new from the dealer. I was trying to eliminate the chance of O2 check engine light.
I have run the truck for over 100 miles on about 5 trips. The first trip I ran it for over 1 hour. No check engine light and no errors on my OBD2 reader.
So far so good. Fingers crossed.

 

When the light comes on just use a spark plug anti fouler on that side.

 

Like this guy?
