MAC Underdrive Pulleys

We all know there are a few high 11 bolt on cars, not many. I think almost all bolt on cars should hit high 12's easy. As for the pulleys ASP 945103 is what's been on my car over 4yrs. It has the integrated balancer.

yes, I am going to be happy with high to mid 12s (like I said my last post), once I do a LOT more bolting on. I plan to go with Pacesetter Longtubes. I am still shopping around a little bit for those. Again, I am going TD, no cats, and some kind of higher flow muffler for each side. It is an IL car (yes, I live in CA right now, but I am a Marine and not a CA resident), and I do not have to have a cats, because according to IL DMV, I am not required to (95s and prior are not required).
Elliots94Z, it is an M6, and I am going with Pacesetter Longtubes.
Lt1-XJS, please explain that balancer to me, and how much does the system cost?
Everyone, I have done a little more research... Wouldn't underdriving the accessories be kind of useless, because you are actually adding another pulley to the system which adds more inertia, which would negate any power that was gained? If I am wrong, please explain it to me.

ASP 945103 ($165) from Asp racing. Pulley and balancer are 1 piece. 24% underdrive, weighs less, about 1/2 size of the original. 15% over on the alt. pulley.
