exhaust/catalytic converter

[siege911]

Hey guys, just a quick question:

With a full cat-back, would it be a good idea to purchase a hi-flow catalytic converter as well? Or would this be kinda useless, because I've read that these aren't more than an enlarged test pipe? Also, I've been reading that these are illegal in California, but are they street-legal in all of the other states? I live in OH btw. Thanks.

get an o2 simulator and hollow out your cat. best way to do it, high flow cat is a waste of money. but be4 you hollow out your cat make sure you find a replacemnet first

would a high-flow cat. make the engine light come on in an OBDII?

just swap out the hi flo back to the oem one when you smog.

will the hi flo cat throw a cel..................eventually.............yes.
