Years ago I got an American Thunder exhaust and got rid of the cats. If I get two aftermarket Catalytic Converters, do they work as is?? The car runs good with recently sent out injectors. No smog in Florida.
They should. I've installed a couple aftermarket cats in different cars and they seemed to work as they should. I didn't live in a smog state at the time, so I don't know if they would've worked well enough for someplace like California or anything.... (probably not - California's funny like that)
They do help. I have two high flow cats on my car just for this purpose. Kids wanted to ride with me but they complained about the smell.
State of Tune also plays a role. During cold start warmup, you are richer than usual so that contributes to the smell. Excessive smell could be some mechanical issue (if not tuned) making the car run a bit richer.
