So I'm doing an ls1 swap to my 93 rx7, and in my state any car older than 95 only requires them to stick the hose in the exhaust to check emissions. With that being said, will I only need the stock cats off a Camaro to pass smog because they won't be plugging in?

Should work.

I went with a pair of Magnaflow 59959 3" ID 4" OD 8" long stainless metal-core cats, passed emissions easily
