I am pretty sure the AEM kit comes with the bung and the measurements to make the angle correct for accurate readings.

Boost is pretty high for pump gas. If you’re still on the stock cats, I’d be personally very worried about them.
Even if you don’t want to do headers, a mid pipe and full exhaust would drop the boost and pick up good power. Definitely consider the free flowing exhaust :)
You may not even need a retune but I’m not as familiar with the 2010s.

Question....at max boost it looks like I hit 18-19 lbs....higher than I really wanted...rarely do I take it to 6K and above but I have.

SO at that boost level what can happen to the cats??? Reason I ask is that my exhaust tone has changed somewhat since my tune...and much different from before the last tune.....it is a little louder, deeper and I may have a slight drone now. Can I have blown the baffles in the stock mufflers or does that not happen?? On a 2010 the stock exhaust pipes and muffler tubes are only 2.5 inches versus the 2.75 on 2011 and up.

Yes, you can blow out baffles, but not likely unless you are no lift shifting with some nice fireworks coming from the exhaust.
Cats are more the issue and usually they melt. If you do not catch it in time, it can blow the motor. You will "usually" see indication of this other than sound. There should be drivability issues in some fashion and the cat likely getting too hot.
Don't sweat over a .25" in piping.

Okay...thanks...I already have the 2014/2012 exhaust system almost ready to install ... hopefully to open up my flow and decrease any cat issue.
I just didn't want to sell my older system once it is off if it is damaged in anyway.

You’ll be changing the exhaust soon?
What items specifically?
Minimum I’d be inspecting the cats thoroughly and if
things need to appear in tact, I’d probably hollow them out.
Good luck.

I have everything now....2014 stock pipe with cats - almost new, lethal OTA SS pipes (2.75) and new Ford Racing mufflers for 2011/12..so it is a complete replacement from the manifold back from a 2010 to a 2013/14 - 2011/12 component swap. I live in NY so yearly emissions tests are performed...hollow out the cats may cause a failure. I didn't want to change the rear valence so 2011/12 muffler setup was needed.

Personally I think you are wasting your time swapping the exhaust stuff.
Other than removing cats, you have little to nothing to gain.

I need the cats to pass smog in Cali, do. You know if hollowing the cats out will set off a CEL when the stock tune is programmed back into the car?

I have four cars and too many other things going on...don't want to have to keep swapping exhaust parts on the 500 every year. I already have enough trouble getting them all passed with one bs thing after another by these local garages. This NYS smog/inspection every year is just another scam for the state and garages to milk money from car owners.
I had to either reduce pulley size on the blower or get back pressure down some from 19+. I also want a quiet exhaust - neighbors and local police (Nazi state here). Swapping the components cost me under $1K and I calculated that the flow volume can increase up to 21% with the larger pipes and cats - even 10% would suffice. Hopefully that ends my issues...otherwise I increase pulley size and retune, which I may have to do anyway. I think the Ford Racing mufflers are going to be louder than I wanted.
