Thanks for the offer. I just may take you up on it. For now, I'm just learning and not ready to buy anything yet. I would be grateful for the photos if you want to post them!

After you first remove the crossover pipe, the front manifold comes off from the top.

The rear one will take a little longer and you will have to lower the exhaust and remove the downpipe first. Then it can be removed from under the car. Jack up the car and support on jackstands. It is better if you have 4 stands so you can get the rear up also. Just 4 bolts and the entire exhaust system can be lowered onto the floor to make a lot of room.

The dealer sells the exhaust bolts in packs of 5. Be careful. I stripped the crossover flange stud bolt taking it off...but didn't care because I had new headers.

I didnt drop my exhaust, just took the bolts off from the manifold/downpipe. An air impact is a very useful tool in this project. The front is cheese, and like Bullet said the rear is more involved. Prepare to remove all sorts of useless brackets and spark plug wires. Also your oil and tranny stick will probably need to be removed, make sure you got a pan handy to catch all the tranny oil that comes out.

You're right, you can do it without dropping the whole exhaust but I cut off my Cat so it make it easier.
The air impact made it real easy to remove the downpipe nuts. They were tight.
