Meisterschaft / ArmyTrix

After numerous discussions with guys running the full exhaust (mostly G37 owners), I'm nearly convinced that the Meisterschaft is the most aggressive sounding exhaust. I was going F.I., especially with the posted 20/11tq gain on the website. But when I heard the GT Haus it all changed. Just for the heck of it, I called John at Z1 Motorsports before I purchased one just to see what he thought of the exhaust. He told me it offered little to no hp gain. John is a great guy and very knowledgable, but I hate to think such a high end and expensive exhaust offers little to no gain over stock. I've looked for dyno's and no luck. I do plan on going with the Stillen SC after they come out with the new high boost kit. I talked with Mark (from Stillen) and he said the G's and Z's that are running the GT Haus tend to run 10-20hp less than others running different after market setup's. I have seen videos of the Armytrix exhaust and it sounds amazing as well. I know a few guys on this forum are running Armytrix. Any dyno numbers on it yet? Everyone has different taste, but I'm going for the "what in the world just drove by", scare someone type exhaust. The Stillen kit performs better with the stock cats and back pressure so test pipes aren't an option. It's hard to justify spending $2500-$3000 on an exhaust no matter what it sounds like if there is no performance gain. Anyone care to shed some light on this?
