High flow cat?
I'm about to install a new y-pipe. I'm also concidering getting hi-flow cat. Can anyone tell me the advantage and disadvantage of having one. I mean is there a big gain over the stock cat with y-pipe? Appreciate your help max family.

i think must people will say this will not free up much power on a NA car. i have a test pipe but have been thinking about taking it off, replacing with stock cat to see what happens. just not sure, either way i dont think stock cat, high flow cat or test pipe will make or break you. if you have turbo then from what i understand you will get more results

I dynoed before and after adding both UDPulley and hi flow cat (the best cat you can buy [namely the metallic substrate hi flow cat from warpspeed]) and I saw gains that I would reasitically say were ONLY due to the UDP. I think its safe to say (IMO) that the money that you would spend on a hi flow cat is much better spent on something else... like lighter wheels...
