And, quite often with stainless systems, they are a bit flat on power. Possibly due to cost savings using a single pipe, instead of the oe twin mid sections perhaps?
Not such a big deal if the bore is larger to compensate 
Maybe they need two silencer boxes? Dunno, I'm no exhaust expert, but the ones I've encountered on omegas feel low on power and high on noise.
One in particular was very poorly fitted.
I just get the impression the fitters make them to their own convenience. Longlife, powerflow, both the same, lazy arses.
Also;
They can't make the clamp to the cat sections, it seems, so often cut the cats and weld on instead. The system is then specific to that car unless the cats go with them. Which means extra agro of removing cats, and if your 3.2 has no pre cat code you have no idea if your inheriting that problem as well if buying a used stainless hand made system.
Given the relevant costs, agro and life pans of handmade v an Eternal system for example. I'd take the Eternal every time. Even if they don't last as long as gm tc systems.
