what wilbo is trying to find out is "who makes the best high flow core on the market?"
so it needs to do several things:
A, flow well (CFM rating)
B, have a reasonable depth to work efficiently (no point getting a cat if it doesn't do the job its suposed to)
C how long will it last? (surely you don't want to pay for something that will be fubared in 6 months

I know they are the same cat, my point was it would be pointless putting 3.5 in ends on a 3in core. Last time i looked around magic and metal cat only did 4 in cores, although magic have seemed to disappear now.

But i will shutup now or Linden will pwn me
