I have a 3.9 and i want to change my cat to hi flow but am having trouble finding one that is hi-flow.
Right now i have JBA headers, JBA y-pipe, and magnaflow muffler and duals.

Can anyone give me a link or part number for a good high flow cat?

Get a Magnaflow or Carsound cat. There really isn't a true "high flow" cat.

being its only a v-6 (and i'm not bashing by all means),any new cat for v-8's will be a big improvement.

I've looked at the magnaflow and the stock cat side by side and the grid in the magnaflow is only a little bigger. I think the biggest difference is that the stock cat is larger around than the magnaflow, which makes it act like more of a resonator (changing the exhaust note more). I can't really see one flowing better than the other (or the stock cat being super restrictive for that matter....especially on a V6).

You may want to look into a spun metallic cat if you are really concerned about flow.

thanks for all your info....i think i am going to save money and keep the stock cat and buy something more worth while
