I installed my magnapacks lasts night, well at least the axlebacks. I am using the stock H-pipe for now. I might install the midpipe this weekend. With out a lift, install was somewhat a PITA. Since I couldn't loosen the midpipe, getting the axlebacks on was a hassle. The sound is awesome. Deeper and throater than my JBAs but I don't think the magnapacks are as load, but that may because they are not broken in yet. Drone/resonance is not as bad as I thought. My Flow 40series was worse.
