Test pipes replace the catalytic converters. These are BEFORE the exhaust. A catback exhaust will replace everything after the cats, this includes the y-pipe and mufflers. They are 2 diffrent parts.

You won't pass smog without cats. But our cars are new, we don't have to smog for 6yrs. or if you sell it. Just be sure and keep your stock cats, so when smog time does come, you can put them back on.
