Ive never heard of it being illegal in SC. We dont have emissions checks here so theyre ok i believe.

 

they might be legal, but morally, they're wrong lol

 

most states that even if you dont have emissions checks they are still illegal(like FL and NJ). how they would ever catch you i dont know

 

Ditto. Not legal in FL, but nobody checks. I put a high-flow cat on my full-size Bronco so my dog, passengers, and I could drive with the tailgate window down and still enjoy ourselves.

It's your call, but ebay has tons of Catco high-flow cats for $50 or less (incl shipping), which is what I paid for a big 3" in/outlet Catco on the Bronco. High-flow cats are cheap, and you'll have a better chance of hooking up with the cute environmentalist behind you in her Prius.

 

so test pipes are illegal? and the hi-flow cat converter is legal right? cuz soon im gonna be buying a hi flow cat and i am debating if it is legal or not....

 

Yes, I haven't heard anyone complaining about failing the sniffer test in California, etc on the other discussion groups I've been on. It costs a little more for an OBD-II compliant cat for '96+ models, here's what a good 2" would look like for the typical Accord:

It's your call. If you drive a Jeep, convertible, Bronco or anything with open exposure from the rear, you want a cat. There really isn't any difference in power or economy with a high-flow cat vs. a test pipe, just one runs cleaner than the other.
