Help! Demon bolt stripped
Guys,
All bolts are off but the demon bolt and it's now stripped. I made the mistake of installed the passenger cat so I feel like I accomplished something but now I can't get the drivers side off ... Have you guys run into the same thing? What did you do?
Thanks

Heat it with a heat gun or torch if you have one. As much as you can. Apply PB Blaster liberally. Allow it to soak for several hours. Repeat the heating, and applying lube process. Ideally let it penetrate overnight. Lubrication is important so that you don't just snap the bolt head off when you try to back it out. Then try removing it with the extractor. Put it on as squarely as possible and tap it several times firmly with a big hammer to seat it on there good. It should grip as you turn counterclockwise to remove it.
When you put the bolts back in, be sure to liberally us anti seize compound on the threads. so they come out easier next time.

This is what I thought, I have read a few DIY's about this project and they said the same. I read the bolt slides through the Header and threads into the Cat itself. So if the head of the bolt breaks it will come out easily.
I am going to try heating it with my heat gun and applying more PB. I have been applying for a few days already. Thanks Guys.

When I did my FI test pipes, every bolt came out no problem, except of course the aforementioned "demon bolt."
The key to removing it is absolutely 100% without question: HEAT!
I put my car on the lift, got a berzomatic and heated the flange until it was RED. I know it sounds foolish but you want to direct the heat to the flange, not the bolt. You want the flange to expand, not the bolt. When I put my 3ft extension through the engine compartment and put a pipe on the ratchet for some leverage, the head of the bolt snapped off, which wasn't a problem because the cat is threaded not the header. When I removed the old cat, the remains of the bold were still stuck in the flange.
To be honest idk if a heatgun will provide enough heat.

A quarter past stripped
The only re-used hardware is the top stud and nut on each cat if your looking towards the front of the car from underneath. Snapping off the single bolt on each cat made removal easier, since you won't need to thread the bolt all the way out. As long as the problem "bolt" isn't the stud that's needed for reinstallation you'll be okay.

So I drove the car to a muffler shop to see if they could remove that bolt. Another problem came up. My steering wheel is turned to the left slightly when driving straight. I am assuming it has to do with me undoing the Steering Rod to get at this damn bolt. Has anyone else had this issue? This is turning into a headache.
