Has anyone purchased a "complete exhaust system" from Vanagain, or Bus Depot?  I am in need of a new cat, muffler and a few other pieces.. seems cheaper to get the whole system.. that way I have the spare parts for down the road.. 

are these systems a good way to go?  I want to hear it.. the good, the bad, and the ugly..  

Thanks
