Alright - If I were to get a muffler shop to remove my cat and but in a test pipe (I think thats what their called) won't my computer be messed and my CEL will be always on?
Or if I get the test pipe will I be good to go without any other modifications?

more then likely most muffler shops wont put on a test pipe. alot of em have a sign that says. "Dont ask me to remove your cat and i wont ask you to pay the 2,500$ fine" (something along those lines) just get a hiflo cat and you'll also aviod a CEL
