Powerflow and other custom outfits do not use mandrel bends. So you new system could well be more restrictive that the original system.
In a recent Redline issue they tested 3'' systems, a ''crinkle'' bent pipe and a mandrill bent pipe and the crinkle was only slightly down on power as most of the gas flows on the outside of the curve
They had some silly gains on the car though, it was an impreza and they had 30bhp with the off the shelf one

tbf there have been good/bad comments about most of the 'budget' aftermarket exhaust systems
