From all accounts I've heard they are of the highest quality. The 2 video clips I posted give you an idea of what an exhaust with ss magnaflow's sounds like. Granted it's more involved than just replacing a resonator and mufflers. I have a co-worker who has a sig welder (whatever kind can do stainless) but he hasn't used it a lot ( he has tons of welding experiance, just not on stainless). I may have a shop put the resonator on soon ($20) and then do the mufflers later.
I am kinda torn though as I can see how you would see a coffee can/rice look:
