best clamps for exhaust install??

[denaliman]

I have used Eisenmann exhaust on its way. For those who have installed this exhaust what are the best clamps to use? The Eisenmann will not come with the exhaust clamps. Since this is a slip over would a stepped band clamp such as Torco be better than a non stepped clamp? I would like something stainless high quality and beefy to secure the exhaust. I know bmw make a clamp but it is expensive and I think it is designed more for but joints on the performance exhaust.
