!! Stripped Cat Bolt !!

halogodx · 08-01-2011, 03:02 AM

Short question on this topic. Is it possible to go pay a shop just to remove ONLY the two top bolts ? would cost at most $30 and would save you the hassle of stripping it etc ?

Some shops have had the same issues because they think they can just pop the bolt right out. Next thing you know they're torching the thing and charging you 3 hours of labor.

I had two demon bolts on mine...what a ******* ordeal that was. I had the car on the lift 3' up with a guy under holding the socket on the bolt. I was on a 6' ladder with a 2' breaker bar and a floor jack handle as a cheater. I sheared them both off, by far the easiest way to do it.

Soaked mine a couple of times with PB blaster overnight and tackled it the next day by myself. Sheared one off on the pass side. the rest made a lot of noise, but came off.
The Driver' side was the hardest to do. Sure was nice to get rid of those stock cats.
Mine was just on ramps. Wrap a towel around the end of your breaker bar so not to dent the hood if the bolt breaks.

Did you end up using a impact socket ?, if so what size.

I should just take a picture when I get home.

I believe it was a 14mm impact socket. Used that with two straight 1/2" extenders to the Ratchet with a piece of 1" Conduit over the end to give me the force needed to move.
I also have 1/2 impact swivel for the Drivers side.

I have 22,0xx miles. I wonder how this is going to pan out. Easier or harder than most...?

Lol Joy!!! Good luck with that, I also had to resort to cutting one of the heads off w/ a dremel and shaking the hell out of the cat to break it free. The other came off when using a 3 ft breaker bar, a pipe and pushing body weight on it, but busted my hands all up. It's no cake walk that's for sure.

And probably harder since heat and rust will probably play a factor now. Even the O2 sensors are hard to get off once they've been heated/infused into the threading for so many miles.

Super!! lol

I strongly suggest against a swivel. It makes it that much harder. If you take the intakes out you can use straight extensions to remove thus making it a hole lot easier. Plus you don't have to worry as much about the impact socket coming off.
