I drove to work and listened to my truck bog followed by a "THOONK". It shot out of the case and is now in the muffler. Now I need to figure how to compensate the labor to have new ones put on.

While fitting pipe a bunch of wooden looking sticks fell out. I realized it's the material inside. Definitely not the usual catalytic grade stuff. Hopefully the rest stays put until I can order a better quality name brand one. Otherwise outside case and bung are well made, came with a plug.

I installed both cats myself using clamps for now until they get welded on. I installed on my 08 f150 5.4l work truck and have had no issues whatsoever. No codes and run just fine. So gor the other reviews that said they had codes I can attest that I have had none so far.
So I can honestly recommend to buy these and have no worries. We will see how long they do last. I will do another review in 6 months.
