I have a hi flow cat (random tech.) and instead of running a test pipe i was thinking of gutting it so i could get maximum flow but still retain the stock cat look....Would this flow better than a 3 inch pipe?

i had someone ask me the same thing the other day. I would really like to know myself. It would make sense to make more power because it's a larger diameter where the cat is, but it might be too big, and cause backups where the pipe gets small again, lossing power over the test pipe.
