96-97 LT1 guys w/ aftermarket cats come in
First of all, do not turn this into a get LTs festival, im not doing that anytime soon. My stock cats have close to 200K on them. Im not having issues with them yet, but id like to start looking for replacement cats. Visual is not a problem, I just need them to pass the sniffer. Thunderbolts look promising. So if anyone has any input, it will be appreciated.

My brothers Grand Am GT didn't pass because off an aftermarket cat.All aftermarket cats are illegal in CA, is what they told him. Don't replace it with an aftermarket cat if you want it to pass legit.

obviously they are illegal, but they are the last piece to my exhaust system i want to replace while staying visually legal. if i get pulled over, everything will look legal because my headers have a CARB number, cats are still there and my catback will be legal. i want to squeeze as much power out of my setup as possible, this is my last power mod without ripping into the internals
