After completing the reassembly of the car, I drove it down to my parent’s home and picked up my son from school. I noticed a sound that I was instantly dreading. There was a knocking that happened as the engine ran. At first I thought it might be my catalytic converters but thought that can’t be since they are relatively new. Then I thought, ope!, I think my engine is a goner. Then, I realized it was more of a rattle so I went under and could hear vibrations when I banged on the cats with my fist. Oh God. The cats.
After some investigating I came to the conclusion that indeed my cats may be bad. After calling Magnaflow and asking for warranty information, they told me to contact a dealer and buy a new system and send the old one back and if they find that it was defective they would credit me. This was after I had asked if I could take my car down to them to inspect. They declined. So, the going rate right now is nearly $1000 for a new cat system. I went up to Speedway Muffler in Upland. After talking to one of the guys, he said that it may take a while to get the warranty going with Magnaflow and in the end, 99% of the time, they say it is the consumer’s car’s fault. Now I know that they are in business, so I just figured, I should just fix it and be done with it. So they removed the rear cats and indeed they were shot.
Unfortunately, I don’t know how this happened as I don’t remember hitting any debris or speed bumps that might have damaged the units. One of the units had a broken brick and the other brick had detached from the housing.
The shop replaced them with new Magnaflow cats and at this point, we’ll see how long they last. I feel rather blah about it since I had a feeling that Magnaflow would not replace the set easily and I figured that I’d be screwed.
