Removing the cats and have some questions (pic)

So all the bolts came out but how do I take the bolt out once I take the nut off?

That car is in great condition, those cat connections look almost new.

You don't take the "bolt" out, just remove the nut. The "bolt" is a stud that's mounted in the main cat flange. You will replace the stud and the one on the other side with a couple new bolts that will attach your new race pipe to the mid piece (the section on the right) to make the connection to the cat-back system.

Works best with air, but the best way to take a stud out if you need to... is to get two nuts. Spin one down far enough to spin a second one on and tighten them against each other. Then unscrew the hole mess.

It looked brand new under the car. The only rusted bolts were on the heat shield but I don't plan on reusing those. So I threw them in the trash.

So once I un screw all 4 it should just fall out?

The new pipe didn't come with gaskets and can I also get the new bolts at auto zone or lowes?


Also is this the right gasket? Just order 2 right? http://www.autozone.com/autozone/par...225413_0_7472_

The heat shield bolts are almost always a problem but if you managed to get at least most of them out without breaking the bolt you were doing well. I'd hold on to those heat shields if you still can, you never know when they may come in handy - plans can change and usually do.

I'm disappointed with the Rotary Performance people, it seems to me that race pipe used to come with the correct gaskets.
