A good quality MDP does the same thing everytime you turn the car off, and is $30 cheaper, and would no way affect bypass pressure. It catches the particles before they hit the pickup/filter further lengthening the life of a filter on initial start up.

A "good" quality MDP still doesn't have much effect because it has to come in direct contact with the metallic particle. The MDP doesn't go searching out metallic particles in your oil... only the ones it comes in contact and it's highly unlike it'll see every bit of oil. And you don't do it to lengthen the life of the filter, but rather keep micro particle contaminants from causing wear and tear on your motor.
The filtermag would have to be pretty close. Less than an 1/8" away from the bypass spring... It's possible to worry if it was such a small filter, that the magnet surface area somehow the filter just took up the whole area.. or if the magnet moved around, but that actually doesn't happen. Once it's stuck on there, it shouldn't be attached anywhere near the bypass spring and it's stays put, but yeah, your claim is substantiated by anything other than assumptions. Just FYI, I have rebuilt a SR with a filter mag and haven't had issues as of yet and prior to this I had a rebuilt KA motor. I wouldn't go as far as badmouthing it without any actual experience.
