2013 Mustang GT Catalytic Removal Help!!!!
I am installing Pypes Cat delete pypes.
I am having trouble with the passenger side catalytic nut where its held on at the header. I tired using my 90 lbs PSI air ratchet but couldn't break it. I Put the car on Jack stands and heated it from the bottom. (I must need more heat, I applied for 5 minutes 2-3 times in between attempts-I will have to get it glowing red?) I took off my Strut tower brace and was able to reach with about 18" of extensions. Put the breaker bar on it and gave it some torque...Snapped all three of my Universal Joints. Tomorrow I will have to switch from a 3/8" to 1/2" drivers (I would have used 1/2 but I didn't have enough extensions)
Any suggestions?

Yes on the PB Blaster. Aero Kroil if you can find it. 1/2 impact gun with 1 long extension if you can find one. The less extensions the better so it doesn't lose torque through the joints of each extension. And a SIX POINT socket. Do NOT use a 12 point socket unless you want to strip it out. Removing the strut brace and battery will create more room, but I didn't need to with mine.

Let it soak in PB Blaster/Kroil like others have said. I also broke multiple 3/8" tools before learning that 1/2" is the way to go. The bolt was soaking in PB Blaster while I went to hardware store to get 1/2" tools and the nut came loose when I got back from store. Also, it felt like an eternity of holding the impact wrench on the nut before it came loose so hold it for a good while.

use a good 1/2" impact, with an impact swivel (not one of the chrome pieces of junk) and 1 extension that is long enough to reach. this will minimize the twist and will get more torque to the fastener.

An Air ratchet will at most provide 40-50 ft/lbs of breaking torque. Nowhere near enough to break loose an exhaust bolt.
An Impact gun will typically provide in excesss of 150 ft/lbs+ of breaking torque.
Keep in mind the extension will take away some of the power of the gun so make sure it's a tight fit on the gun's nose and if you use a swivel, keep it as straight as possible. Personally I would use a wobble extension at most or just do it by hand, but that's just me.
6 pt socket (preferably impact rated) is best, otherwise you may shatter even the best 6 point chromolly.
If all you have is chromolly sockets, whichever one you use, wrap it in duct tape. If it shatters, it will prevent it from throwing shrapnel.

Are using an impact gut or air ratchet? Two totally different things.
An Air ratchet will at most provide 40-50 ft/lbs of breaking torque. Nowhere near enough to break loose an exhaust bolt.
An Impact gun will typically provide in excesss of 150 ft/lbs+ of breaking torque.

Had the same problem. I had buggered up that one nut pretty good because I couldn't get a good grip on it. Took my car to an exhaust shop and paid $40 to have that one nut removed. Drove it back home and did the rest myself.
