Extra hands help out a lot, and an air ratchet will make it much easier IMO.
This is only my opinion, and is not based on any hard facts - but the work required to remove the manifolds is way more than the payoff you get from gutting them. Heck, I did mine in like 2 hours on the car and still feel it was wasted effort.
I think his concern was the risk of damaging the engine with particles of catalyst material. From that perspective he has a valid point. Its just a matter of how much work is too much when it comes to risking your engine.
I did mine on the car before everyone started pointing how bad an idea it is. I know it is a bad idea now, but I got lucky and had no issues.
My point was that I don't think the benefit is worth the effort, even if you take the easy way out and do it on the car.
