high flow cat worth it?
would it be worth it for me to do a header back exhaust with a magnaflow high-flow cat? Im already planning a cat back with a flowmaster and i figure it cant be much more money for the pipe from the header. im thinking its gonna cost me a good $300 for all of the pipes and another $100 to get the muffler and cat here so is the $400 worth the new exhaust system?

what!....where are you getting the headers from? I spent about $165 on a delta flow s.s. 50 series and high flow cat. I thought any of the good headers for the 3.0 were around $500

A cat back is pretty pointless for any car. Unless you have good flow the whole way through then a cat back won't help much. A header is a good idea, but you could save money on the cat by buying a universal fit V8 cat since its designed for higher flow.

Care to back these claims up with some numbers?

I think you'll find most all cats are now "high flow" designs. That term came about in the early days of cats. The early cats used beads then a new and improved honeycomb design came out that was less likely to clog up and that flowed exhaust better. So those cats were advertised as "high flow". I've looked at a few different Toyota cats and they are all essentially the same inside. All stainless steel, all honeycomb matrix and they all look like they would flow equally as well. You can play around with putting a larger cat on or one with larger inlet and outlet pipes. That is probably all the current "high flow" cats are anyway. If the old cat is not plugged up, may as well run it until it is shot then replace it.

also dont know the laws where you live, but here in CA you cannot remove the cat if it isnt bad or has so many xxx amount of miles on it, if you do, you face jail time and/or a huge fine....

I am going to have to agree with 4crawler. Unless your Cats are shot, don't replace them. The power gains and sound comes mostly from the headers and the exhaust. If you are going for power save the money on the cats and buy a high flow filter or wider throttle body, you will see more power from them than you ever will from a new cat. Unless of course you have already done those things, and have money to blow, then go with some high flow cats.
