GT350 Exhaust Failure

[Cypherious]

Don't know if it has a torque spec. Guess you will be having a chat with that dealer?

It's coming. With pictures now.....

Got under the car while up at my parents place in Blue Ridge & found the problem in a few seconds. It was the loose counter weight on the catalytic converter assembly. At Autozone now picking up a couple supplies and should have confirmation shortly.

Btw... does anyone know the torque spec for this bolt? View attachment 502954 View attachment 502955

Dude!!! I was going to tell you to check that out but I couldn’t imagine with them swapping the exhaust that they didn’t catch that!
What a joke!

I’d take pictures of it, go back to dealer. No way in hell did they check that and not find it. I doubt they even looked under the car.

Holy cow......avoid that dealer like the plague. At least your car sounds super sweet now?

Use the German torque spec, gudntight

OP, I'm reading the service manual and the Catalytic Converter RH/LH only provide the below for torque specs:
1) clamp nuts.
Torque: 35 lb.ft (48 Nm)

That's all we get. Which in any of our cases, we'd have to put on our engineering hat on and decide how much torque do we safely think we could get by. I'd say 16-18 LB/FT since that's what the 2016 oil filter can handle (to your discretion). May be worth contacting Ford Performance and seeing if they can chime. I spent the last 30 minutes looking for the thread where I originally saw this problem to see if he had the torque specs for it but I couldn't find the thread.

There's always the loctite red torque spec. Guaranteed not to back out!

Perhaps safety wire it. Take the nut off, get a 3/32 drill bit. Drill hole into nut then install and safety wire it. It won’t come loose again after that.

I might be the first here, but I have a Ford dealer (Sun State Ford) telling me I had an exhaust baffold go bad inside one of my mufflers. Car is a 2016 GT350 with 27k miles. Just outside of the 3 year/36k and I'm told I'm going to have to eat a ~$2,600 repair (cost of OEM catback system plus labor). Likely going aftermarket based on cost instead.

I've had cars with as much as +100k miles and never a single exhaust problem. Has this happened to anyone else with a GT350 (don't care about the GT Owners - no offense)?

I have my original stock exhaust, less valves that I took of my 2017 GT350 at 5000 miles. You can have it for $500.00 plus shipping from PA. I can get a good deal on shipping from my old company.
