Is it possible to remove the stock exhaust manifold in one piece by pulling it up through the engine bay? The bolts where the two pieces connect are rusted too much and I cant get my arm/dremel up there to cut them off.

I've tried PB blaster, let it soak overnight and re-soaked before removal attempt. Still can't get them to budge.

I was thinking that I could just pull the manifold up and then angle it so that it can be removed from the top without removing those bolts, but I wanted to know if it was even possible before I start cutting away at the bolts on the cat which are even worse.

 

Good luck trying to accomplish that. Im gonna be doing the same proceedure soon. I was wondering same thing but it looks like its just not possible without moving the radiator and the radiator fans. There is some other crap in the way to that would make pulling the headers down from the bottom of the car. And the down pipe is just to long to angle it up from the top. I got me an angle grinder for lke 35 bucks. i needed it cause my nuts are rusted on to hard. (on the cat)

So they are gonna get cut off. But keep us posted if you are able to pull that out with out trying to hard
