Magnaflow direct fit cats

So I bought my 2007 WK with the hemi on Wednesday and I have codes P013C and P013A. I've read what can cause this so I went under the jeep today to look for leaks and found what appears to be a magnaflow direct fit cat setup. It looks very well made and pretty much brand new. I did find a leak where it connects to the giant muffler/resonator so I tightened the collector down and tightened the clamp before the y section as well. Would a leak after the O2 sensors cause this code? I was able to clear the codes with the torque app and cycling the DTC code reader on the dash. I've ordered two new NTK O2 sensors, supposedly they made the OEM ones and work better than Bosch. Anything else I should look for?

I just went thru this. and the NTK o2 sensors are shit!!! They are made in Japan and they just kept throwing a code for me, even after replacing the cats. I had went to get the Mopar. Which are still made by NTK but are made in the USA. ANd I have yet to see a code.

I would just buy 2 cats and have them welded in rather then spending all that money for the Mid section. And the downstream o2 sensors are the one that tell if the cats are bad or not. So I would start there with 2 new downstream o2 sensors. and if u still got code then go replace the cats.

But I just went thru this and that is what happened to me.

Re: Magnaflow direct fit cats

That's funny because everywhere I read online said they were better than the other brands on Chrysler vehicles. I bought the 2 to replace the rear ones and the mid pipe is already replaced so its brand new. I'm going to take it apart and put it back on and see if it fixes any leaks there may be

what you read isnt always correct. But hey to each there own. I went thru it for a few weeks and Im telling u from exp. those NTK are gunna give you issues.

And If it is a new mid, just get new cats and have old cut off n newones welded in..

And what is gunna fix a leak? you could get soapy water spray where u think has a leak n watch it bubble .

Re: Magnaflow direct fit cats

I think it is leaking where it connects to the stock exhaust and possibly the headers/ manifolds. I'll try the NTKs as they are already on there way. If they suck back to amazon they go

Replaced both O2s and drove it 3 miles and just the po13a came back. Cleared the codes and drove 22 miles and both codes came back. This is so frustrating. Cats and midpipe are brand new and now so are the O2s.

You were already advised you would have this problem running the Japan made sensors, so swapping to the USA made ones sounds like the best thing from his experience.

Re: Magnaflow direct fit cats

Less related note, I have those mids and cats on my rig, and I found that the flange connector at the rear was too big for the OEM setup by a half inch. Caused a huge exhaust leak until I cut out the flange and put in a reducer. May or may not be of any help, thought I'd let you know.

Re: Magnaflow direct fit cats

Did you have any codes with that leak? I would think a leak after the O2's wouldn't cause a code. I do know mine is leaking there, I can feel the air and condensation drops from there.

Re: Magnaflow direct fit cats

I've tried to tighten it while using a Jack to lift it higher and tighter and there is still a leak. Guess I'll get a shop to weld it on
