You need a better impact, mine does 600 ft/lbs at 120 psi. I can get more with a breaker bar, but even they can break above that.

That's what you think. I don't think they ever truly live up to their advertised torque. Also what kind of air lines, fittings and air compressor are you using? Mine is advertised at 600 ft/lbs. in reverse and 400 ft/lbs. in forward. With our restrictive air fittings (with a massive screw-type air compressor) it only reaches about 400 ft/lbs. in reverse and about 215 ft/lbs. in forward. If I had high flow fittings on it, it would be closer to advertised torques.
As far as the breaker bars, you can get much more torque out of a large enough breaker bar (and pipe sometimes) than an air gun but like you said, they do break. I've gone through two 1/2" drive Snap-On ones while trying to break loose bolts on a wheel motor (I do hydraulics). This was after heating the housing to loosen them up. Everything has it's breaking point.
