For all the different exhausts I've had Raj, the Magnex 2" has been the worst but for the two things I mentioned above. It seemed the most restrictive, especially at the top end (no doubt thanks to the built-in restrictor half way up its chuff), had the least character in it's note, had a crap rolled in tail and a badge on the exit that was half visible when fitted.
The restrictor probably improved low down torque. I couldn't be sure.
You're right though mate, you have to go with what saves the £'s in today's climate
