I believe when I took my manifolds off I left the cat on.

I'm pretty sure I've heard of people doing that....leaving the cats on the manifold and still getting the whole assembly out. Never did it that way myself but it can't hurt to try....

just break the studs with an impact gun. I did this but my nuts came off instead of breaking the studs

I dropped mine with the cats off, but afterwards realized that leaving them on would have saved me some time. The only problem I had was I also left the pre-cat O2 sensor on when I started to drop the driver's side exhaust manifold. It got caught and I ended up mangling it really bad in order to get the exhaust manifold to drop out.

Be ready to jack the car up REALLY high if you're not using a lift. I've got install pics on my site of my header install if you'd care to check them out.

I just installed the DynamaXX Lt's and took the stock converters off first. Bolts were also difficult. So a sprayed the sh*t off of the bolts w/WD40 and made a wrachet extender with some pipe to get extra torque which worked fine for me.

I left mine on....just make sure the car is high enough up so that you dont have any problems getting them out

on my driver side i just jacked up the car with two 4x4's on top of eachother and it was high enough to get the manifold out with the cats. On the passenger i just used a 3/8 ratchet with an extension and yanked on it and just snaped all 3 studs
