I scrolled thru the older threads and haven't seen this addressed.
Has anyone out there suffered a catalytic converter failure? It appears I have. Last night I got the "stones in coffee can" sound at a stop sign. 2012 PP V6 with CAI and Pypes muffler delete (58,000 mi).
I checked all the usual rattle points to no avail. Once I hit just forward of drivers cat W/rubber mallet I was able to recreate the sound.
FMC says cats are covered 8/80k but I'm wondering if Pypes will be questioned.
That is interesting that an OEM cat kinda faild. I know a part of the shelf can sometime be defective.
-I guess its not easy to swap in a muffler, huh?
-I have an idea if you are trying not to draw attention to the exhaust tone (They will have it up on lift anyway), is to insert one of those insertable mufflers used at tracks. It's supposed to work and sound awesome.
This is the one i used on the green Mustang. Inserts into tail pipe, removable, just lube it slightly that wont smoke or stink easily.
Internal Pipe Diameter -Measure couple of times with caliper.
I've replaced a few cats on v6 and v8 mustangs at work. Almost all of the times they where covered under emissions warranty. And the fact that they had aftermarket mufflers did not affect the warranty at all. A cold air intake might though depending on your dealership
I'm sorry, I thought they were known for huge longevity, well made.
Only because I build and own only the older SN95 gen & the Fox Body. Suprising that a huge number still operate on original OEM.
Now, I know for a fact that catalytic converters, O2 sensor (up & down stream), do slowly deteriorate, become less calibrated over time.
