We had a problem with one of the nuts holding the cats to the exhaust manifold. We tried penetrating oil and a torch but we ended up cutting the nut off. This is pretty unusual for a California car.
You can see in this picture that the Magnaflow cats have bigger tubing. The passenger side has one post cat slip joint so the cat can be in two pieces. This makes it a lot cheaper to ship. We noticed that the Magnaflow cats were longer and bigger in diameter than the OEM parts.
On the driver’s side, you can see the larger tubing. The cats are also shaped a little differently with the Magnaflow parts being longer, wider, and more tapered in construction. Maybe the bricks in the cats have more frontal area for less backpressure.
The OEM cats have double wall tubing with a smaller internal diameter, the Magnaflow part has a single wall and more flow area.

In Canada big OEM catatytic converter like this are worth a couple hundred dollar. A lot of people buy them on marketplace. But it is probably against the law in California to sell used coverter….
So EO# D-798-14 does not belong to Magnaflow which is the reason why the catalytic converter cans look different. They could have a cross marketing agreement with AP exhaust, which is why they are using their catalytic converter on their direct fit parts. 75 dollars to recycle your catalytic converter is a joke. if it was only worth 75 dollars catalytic converter thieves wouldn’t be stealing them off vehicles. Magnaflow is making a killing on recycling your old cats.
It’s actually $150 bucks and I don’t really care, was going to throw it away and Magnaflow makes it convenient to get rid of it.
I agree, finding a scrap yard and then getting to it, haggling, and getting whatever they give you is not worth the trouble if you can just send the catalytic converter back. It’s nice to get a little extra moolah on top of it, with $150 you can probably fill the tank on that Tundra from E lol.
maybe half tank! The good thing is the new cats gave me 2 more mpg.
Right👍🏿
Love that O2 sensor socket! Mine sticks out too far to be of much use in tight spaces.
